Vaccine development

Innovative tools to accelerate vaccine research and development

Viral & host genomics | Bioinformatic analysis | Clone vaccine targets | Express & purify vaccine targets | Immunize mice | Clinical trials

SARS-CoV-2 research is happening at breakneck speed, and scientists are trying to identify epitopes that could trigger an immune response to the virus, an important step in the development of novel vaccines. Takara Bio offers an array of innovative technologies to support this endeavor. The development of a vaccine involves an analysis of the viral and host genomes using sequencing and bioinformatics to identify potential targets, cloning and isolation of candidate epitopes, testing immune response in animal models, and finally conducting clinical trials with the lead candidates.

Viral development workflow


Viral and host genomics

Viral and host genomics

Whole-genome sequencing of the SARS-CoV-2 virus can provide valuable information on potential antigenic epitopes that could trigger an immune response. Takara Bio's SMARTer Stranded Pico v2 kit has been used in China to sequence SARS-CoV-2, providing a full-length viral genome sequence. Immune profiling of COVID-19 infected or recovered individuals via RNA-seq can provide additional information to further fuel the process of antigen and vaccine target identification. Our highly sensitive SMARTer Human BCR and TCR profiling kits can be used to monitor changes in BCR (B-cell receptor) and TCR (T-cell receptor) clonotype repertoires throughout disease progression, from infection to recovery.

For single-prep purification of SARS-CoV-2 RNA from bodily fluids and swab samples, we recommend NucleoSpin RNA Virus, which employs a streamlined 30-minute protocol. For high-throughput processing, NucleoMag Pathogen employs scalable, automation-friendly magnetic beads, with scripts available for many common platforms.


Bioinformatic analysis

Bioinformatic analysis

The next step is bioinformatic analysis of the viral genome and host BCR and TCR immune profiles to reveal SARS-CoV-2 antigens and select vaccine targets (viral surface receptors). Takara Bio Immune Profiler Software can be used along with the SMARTer Human BCR IgG IgM H/K/L Profiling Kit to parse out information about clonotype numbers and V(D)J sequence information.


Cloning vaccine targets

Clone vaccine targets

Researchers can speed up viral receptor and vaccine construct generation using NucleoSpin gel and PCR cleanup and plasmid purification kits as well as our In-Fusion Snap Cloning technology for high-throughput cloning:

  • Highly efficient—over 95% cloning efficiency for inserts ranging from 0.5 to 15 kb
  • Sequence independent—clone ANY insert, into ANY vector, at ANY locus
  • Seamless construction—no extra base pairs (or scar sequences) at cloning junctions
  • Versatile—multiple-insert cloning and site-directed mutagenesis with a single kit

Researchers have already published work utilizing In-Fusion HD Cloning technology within their workflows to study and develop vaccines against coronaviruses, including SARS-CoV-2:

  • Abbott, T.R. et al. Development of CRISPR as an Antiviral Strategy to Combat SARS-CoV-2 and Influenza. Cell. 181, 865–876 (2020).
  • Letko, L., Marzi, A., & Munster, V. Functional assessment of cell entry and receptor usage for SARS-CoV-2 and other lineage B betacoronaviruses. Nat. Microbiol. 6, 562–569 (2020).
  • Huo, J., et al. Neutralization of SARS-CoV-2 by Destruction of the Prefusion Spike. Cell Host & Microbe. Under review (2020).


Express and purify vaccine targets

Express and purify vaccine targets

NucleoSpin 96 Plasmid Transfection-grade is a popular choice for manual or automated high-throughput purification of expression constructs. When it's time for scale-up, NucleoBond Xtra midi and maxi kits combine gravity flow filtration and anion-exchange technology to deliver higher yields in less time than conventional alternatives. Our BacPAK Baculovirus Expression System uses a baculovirus backbone to express your protein of interest for vaccine development. This technology is easy to scale up, has high levels of protein expression, and is nonpathogenic to humans. In addition, the target proteins produced with this system are similar in structure, biological activity, and immunological reactivity to the naturally occurring protein. Once expressed from these purified constructs, his-tagged vaccine candidate proteins can be rapidly purified using our performance-validated cobalt and nickel resins or our revolutionary Capturem high-capacity membrane-based purification technology:

  • Fast, convenient workflow—5- to 30-minute room-temperature protocol using convenient spin columns/plates/filtration devices featuring Capturem nickel-functionalized membranes
  • High purity—small bed volumes trap fewer contaminants
  • Compatible with a wide range of additives—including EDTA, DTT, BME, glycerol, TCEP, etc. (see compatibility table)
  • Versatile—easy purification from mammalian/bacterial cell lysates and supernatants

Researchers have already published work utilizing our Capturem His technology within their vaccine development workflows:

  • Do, V. T. et al. Recombinant adenovirus carrying a core neutralizing epitope of porcine epidemic diarrhea virus and heat-labile enterotoxin B of Escherichia coli as a mucosal vaccine. Arch. Virol. 165, 609–618 (2020).
  • Martínez-Hernández, S. L. et al. An anti-amoebic vaccine: generation of the recombinant antigen LC3 from Entamoeba histolytica linked to mutated exotoxin A (PEΔIII) via the Pichia pastoris system. Biotechnol. Lett. 39, 1149–1157 (2017).

Immunize mice with vaccine targets,

Immunize mice with vaccine targets, screen sera for antiviral activity, and optimize promising candidates

Takara Bio's SMARTer Mouse BCR and TCR profiling kits can be used to speed up the process of immune sera screening for antiviral activity of target vaccines by monitoring changes in the BCR and TCR clonotype repertoires. Promising vaccine candidates are further optimized by analyzing and comparing antibody and T-cell responses in the vaccinated animals prior to and upon exposure to virus.


Clinical trials with selected final vaccine candidates

Assess effectiveness of selected final vaccine candidates in clinical trials

Monitoring the immune response is key to assessing the effectiveness of the final vaccine candidates. BCR and TCR repertoire profiling by NGS allows precise monitoring of clonotype changes and the identification of vaccine-specific clonotypes.

744970.50 NucleoMag® NGS Clean-up and Size Select 50 mL USD $770.00

NucleoMag NGS Clean-up and Size Select employs scalable, automation-friendly magnetic bead technology to enable efficient cleanup of DNA or RNA fragments. The flexible protocol enables processing of 50–150 µl input volumes and allows for enrichment of fragments ranging in size from 150–800 bp. NucleoMag NGS Clean-up and Size Select consists of paramagnetic beads suspended in binding buffer that selectively bind DNA and RNA fragments based on the volume ratio of bead suspension to sample. After magnetic separation and removal of supernatant, the beads are washed with ethanol followed by a short drying step. Following elution in low-salt buffer or water, the highly purified DNA is free of contaminants such as nucleotides, primers, adapters, adapter dimers, enzymes, buffer additives, or salts, and can be used directly in downstream applications. NucleoMag NGS Clean-up and Size Select provides comparable performance and employs the same dilution ratios for size selection as magnetic bead-based solutions from other providers, such that it can be incorporated in existing workflows without the need for protocol adjustment or optimization.

Cat. # 744970.50 consists of a bottle containing 50 ml of bead suspension.

Tunable selection of DNA fragments in a given size range using NucleoMag NGS Clean-up and Size Select

Tunable selection of DNA fragments in a given size range using NucleoMag NGS Clean-up and Size Select
Tunable selection of DNA fragments in a given size range using NucleoMag NGS Clean-up and Size Select. NucleoMag NGS Clean-up and Size Select can be used to isolate DNA fragments of a given size within a target range of ~150�800 bp. Selective binding of DNA fragments above a designated size cutoff is achieved by applying NucleoMag beads to the sample at a predetermined dilution ratio. This approach can be applied once or twice to perform single- or double-sided size selection. In the latter case, an initial round of bead purification is typically performed to bind and remove fragments above the upper size cutoff, and a second round of purification is performed to bind and retain fragments above the lower size cutoff. Dilution ratios used for size selection with NucleoMag beads are similar to ratios employed by size-selection beads from other providers, such that NucleoMag beads can be incorporated in existing NGS library preparation workflows without protocol adjustment.

Library preparation workflow and PCR strategy for TCR profiling using the SMARTer approach

Library preparation workflow and PCR strategy for TCR profiling using the SMARTer approach
Library preparation workflow and PCR strategy for TCR profiling using the SMARTer approach. Panel A. Reverse transcription and PCR amplification of TCR subunit mRNA sequences. First-strand cDNA synthesis is primed by the TCR dT Primer and performed by an MMLV-derived reverse transcriptase (RT). Upon reaching the 5′ end of each mRNA molecule, the RT adds non-templated nucleotides to the first-strand cDNA. The SMART-Seq v4 Oligonucleotide contains a sequence that is complementary to the non-templated nucleotides added by the RT, and the oligo hybridizes to the first-strand cDNA. In the template-switching step, the RT uses the remainder of the SMART-Seq v4 Oligonucleotide as a template for the incorporation of an additional sequence on the end of the first-strand cDNA. Full-length variable regions of TCR cDNA are selectively amplified by PCR using primers that are complementary to the oligonucleotide-templated sequence (SMART Primer 1) and the constant region(s) of TCR-α and/or TCR-β subunits (TCRa and/or TCRb Mouse Primer 1). A subsequent round of PCR is performed to further amplify variable regions of TCR-α and/or TCR-β subunits and incorporate adapter sequences using a TCR Primer 2 Forward HT Index and a TCRa and/or TCRb Mouse Primer 2 Reverse HT Index. Included in the primers are adapter and index sequences (Read 2 + i7 + P7 and Read 1 + i5 + P5, respectively) that are compatible with the Illumina sequencing platform. Following purification, size selection, and quality analysis, the TCR cDNA library is ready for sequencing. Panel B. Semi-nested PCR approach for amplification of TCR-α and/or TCR-β subunits. The primer pairs used for the first round of amplification capture the entire variable region(s) and most of the constant region(s) of TCR-α and/or TCR-β cDNA. The second round of amplification retains the entire variable region(s) of TCR-α and/or TCR-β cDNA and a smaller portion of the constant region(s). The anticipated size of the final TCR library cDNA (inserts + adapters) is ~700–800 bp.

Assessment of TCR diversity in mouse spleen samples with the SMARTer Mouse TCR a/b Profiling Kit
Assessment of TCR diversity in mouse spleen samples with the SMARTer Mouse TCR a/b Profiling Kit. Panel A. To compare TCR diversity between the spleen's general T-cell population and purified CD4+ T cells, total splenocytes were isolated from spleen and divided into two groups. The first group was left untouched, and the second group was subject to CD4+ T-cell purification (see Methods section for details). Total RNA was extracted from the total splenocyte group and the group enriched for CD4+ T cells, and each RNA sample was used for library preparation. Panel B. Proportion of on-target reads mapping to TCR-α or TCR-β CDR3 sequences. Panel C. Rarefaction curves showing the relationship between read depth and the number of unique clonotypes identified for TCR-α (left) and TCR-β (right). When a curve starts to flatten off, the number of unique clonotypes identified is reaching saturation. Dashed lines show the theoretical number of clonotypes as the number of reads increases.

Panel B. The immune tissues showed the highest TCR-α clonotypic diversity, while the large intestine showed the lowest diversity. This indicates that the large intestine has the lowest T-cell infiltrate. Panel C. Abundance of the TRAV3-2-TRAJ58 clonotype, expressed as a percentage of all reads mapping to any TCR-α or TCR-β clonotype, across tissue types and ages. Panel D. Abundance of the TRAV16N-TRAJ56 clonotype, expressed as a percentage of all reads mapping to any TCR-α or TCR-β clonotype, across tissue types in the 38-week-old mouse.

BCR development.

BCR development.

BCR development. The progenitor cell undergoes recombination of V, D, and J segments in the germline, which generates two identical heavy chains. Recombination of V and J segments generates two identical light chains. Random nucleotide additions or deletions at the junctions of the V, D, and J segments provide additional diversity. Furthermore, B cells activated by immune responses undergo somatic hypermutation (SHM), in which additional point mutations are introduced.

SMARTer Mouse BCR IgG H/K/L Profiling Kit workflow.

SMARTer Mouse BCR IgG H/K/L Profiling Kit workflow.

SMARTer Mouse BCR IgG H/K/L Profiling Kit workflow. Panel A. First-strand cDNA synthesis is dT-primed (BCR dT Primer) and performed by the MMLV-derived SMARTScribe Reverse Transcriptase (RT), which adds nontemplated nucleotides upon reaching the 5' end of each mRNA template. The BCR Oligonucleotide anneals to these nontemplated nucleotides and serves as a template for the incorporation of an additional sequence of nucleotides into the first-strand cDNA by the RT (this is the template-switching step). The BCR Oligonucleotide contains sequence from the Illumina Read Primer 2, serving as a primer-annealing site for subsequent rounds of PCR, and ensuring that only sequences from full-length cDNAs undergo amplification. Panel B. The first PCR uses the first-strand cDNA as a template and includes a forward primer with complementarity to the Illumina Read Primer 2 sequence (BCR Primer 1V), and a reverse primer that is complementary to the constant (i.e., nonvariable) region of BCR heavy or light chains (mBCR Primers 1H, 1K, or 1L). The chains are amplified in separate reactions. By priming from the Read Primer 2 sequence and the constant region, the first PCR specifically amplifies the entire variable region and a considerable portion of the constant region of BCR heavy or light chain cDNA. The second PCR takes the product from the first PCR as a template and uses semi-nested primers (mBCR Primers 2H, 2K, or 2L) to amplify the entire variable region and a portion of the constant region of BCR heavy or light chain cDNA. As in PCR 1, the BCR subunit chains are amplified in separate reactions.

Highly specific amplification of Ig chains.

Highly specific amplification of Ig chains.

Highly specific amplification of Ig chains. Libraries containing BCR G and K chain transcripts were generated using the SMARTer Mouse BCR IgG H/K/L Profiling kit, starting with 10 ng of RNA isolated from a hybridoma developed in-house (10E8) and two manufactured ATCC hybridoma samples (HB-8117 and TIB-127). Panel A. Bioanalyzer traces showing gene-specific amplification of G, K and L chains for each hybridoma. Peaks labeled "LM" and "UM" correspond to DNA reference markers included in each analysis. Panel B. Mapping metrics were determined using MiXCR software (version 2.1.81.8; software not provided with kit) and aligned against all Ig reference sequences, with a clone fraction threshold of 0.01%. V, D, and J IMGT allele outputs, alignment scores and consensus CDR3 amino acid CDR3 for the top heavy (G) and light (K) chain clone for each hybridoma are displayed. For cases in which the MiXCR software determined the presence of more than one V, D, or J allele, all determined alleles with alignment scores are shown.

PCR cycling and pooling workflow.

PCR cycling and pooling workflow.

PCR cycling and pooling workflow. After RT step, the user amplifies the G, K, or L chain transcripts in separate reactions. Each amplification uses 5 µl of the RT reaction. Following the first PCR, 1 µl of each PCR is used in a separate PCR reaction (PCR 2) to add the same sequencing indexes to each amplified chain for a given sample, but distinct indexes for each different sample. After this final amplification in PCR2, the user may validate each product on a Bioanalyzer or other fragment analysis system. The user then has the flexibility to choose which amplified BCR chains to pool for sequencing.
