tdTomato fluorescent protein

Plasmid for expression of TdTomato fluorescent protein

tdTomato is an exceptionally bright red fluorescent protein—6X brighter than EGFP. tdTomato's emission wavelength (581 nm) and brightness make it ideal for live animal imaging studies. The tdTomato fluorescent protein is as photostable as mCherry (Shaner et al. 2004). Sequence mutations were introduced into a monomeric variant of DsRed through directed evolution by the Tsien lab in order to produce tdTomato.

The tdTomato fluorescent protein is as photostable as mCherry (Shaner et al. 2004). Sequence mutations were introduced into a monomeric variant of DsRed through directed evolution by the Tsien lab in order to produce tdTomato. This very bright red fluorescent protein was made even brighter by creating a tandem dimer version, the tdTomato fluorescent protein. Because tdTomato forms an intramolecular dimer, it is considered monomeric (Shaner et al. 2004).

This lentiviral expression vector encodes the tdTomato fluorescent protein tag. This very bright red fluorescent protein is a genetic fusion of two copies of dTomato, which was specifically designed for low aggregation. It adopts an intramolecular tandem dimer structure that contributes to its exceptional brightness, yet it behaves like a monomer. Inserting a cDNA in the MCS downstream of the tdTomato coding sequence joins your protein of interest to the C-terminus of the tag, and allows the fusion protein to be tracked and studied in transduced cells.

To package the vector into high-titer, replication-incompetent lentivirus, we recommend using Lenti-X Packaging Single Shots and the Lenti-X 293T Cell Line. The resulting lentivirus can then be used to transduce virtually any mammalian cell type.

ptdTomato encodes a tandem sequence of the dimeric red fluorescent protein, Tomato. In this vector, the tdTomato coding sequence is flanked by unique restriction sites at the 5' and 3' ends, making it easy to excise the sequence for transfer into another vector. The ptdTomato vector contains a lac promoter sequence, and therefore can be used to express tdTomato in E. coli. It is primarily intended to serve as a source of tdTomato cDNA.

The DD-tdTomato Reporter System includes the pDD-tdTomato Reporter vector and Shield1. The pDD-tdTomato Reporter is a promoterless vector that allows you to insert your promoter of interest upstream of the red fluorescent protein tdTomato, tagged at its N-terminus with the ProteoTuner destabilization domain (DD). The DD causes the reporter protein to be rapidly targeted to and degraded by proteasomes. This very efficient and controllable destabilization method will minimize background fluorescence from leaky promoters prior to promoter activation.

To analyze promoter activity, a candidate inducer is added to the medium along with Shield1, which effectively stabilizes the reporter protein and allows it to accumulate. As a result, only the reporter molecules expressed during promoter induction will contribute to the fluorescence signal, providing a considerably higher signal-to-noise ratio than that obtained with non-destabilized or constitutively destabilized reporter systems.

DD-Fluorescent Protein promoter reporters provide a much greater fold increase in signal intensity than traditional fluorescent protein reporters, which do not contain the DD. HEK 293 cells were transfected with plasmids encoding the following reporters: CRE-tdTomato, CRE-DD-tdTomato, CRE-ZsGreen1, and CRE-DD-ZsGreen1. 24 hr later, the cells were stimulated with 10 μM forskolin and simultaneously treated with 1 μM Shield1. After 4.5 hr, fluorescence intensity was measured via flow cytometry, and fold induction was calculated. The tdTomato and ZsGreen1 reporters containing the DD had three- and six-fold greater fluorescence intensity respectively, than the versions without the DD, due to the latter’s increased background levels.

pEF1α-tdTomato is a mammalian expression vector that constitutively expresses the red fluorescent protein tdTomato, even after stable integration of the vector into the host cell genome. Stable, constitutive expression of tdTomato is driven by the human elongation factor 1 alpha (EF1α) promoter, which allows the protein to be expressed without the transgene silencing associated with CMV promoters. The vector, which lacks an MCS, is designed to be used for cell labeling or as a marker of transfection efficiency.

The Lenti-X DD Red Reporter System includes the Lenti-X DD-tdTomato Vector Set and Shield1. The Lenti-X DD-tdTomato Vector Set includes two lentiviral expression vectors (a reporter vector and a control vector) that produce high titers of recombinant lentivirus, which can efficiently transduce both dividing and nondividing mammalian cells. The system provides enough reagents for 16 packaging reactions. The pLVX-DD-tdTomato Reporter Vector is a promoterless vector that allows you to insert your promoter of interest upstream of the red fluorescent protein tdTomato, tagged at its N-terminus with the ProteoTuner destabilization domain (DD). In the absence of the membrane-permeant ligand Shield1, the DD causes the reporter protein to be rapidly targeted to and degraded by proteasomes. This very efficient and controllable destabilization method minimizes reporter background fluorescence from leaky promoters prior to promoter activation. To analyze promoter activity, a candidate inducer is added to the medium along with Shield1, which binds to the DD tag and thereby stabilizes the reporter protein and allows it to accumulate. As a result, only the reporter molecules expressed during promoter induction will contribute to the fluorescence signal, providing a considerably higher signal-to-noise ratio than that obtained with nondestabilized or constitutively destabilized reporter systems. Cells used to monitor uninduced promoters (e.g., the negative control) will be treated with Shield1 alone.

The pLVX-IRES-tdTomato Vector is a bicistronic lentiviral expression vector that can be used to generate high-titer lentivirus for transducing dividing or nondividing mammalian cells. The vector contains an internal ribosomal entry site (IRES) which allows a gene-of-interest and the tdTomato fluorescent protein to be simultaneously coexpressed from a single mRNA transcript. When used with the Lenti-X Packaging Single Shots and the Lenti-X 293T Cell Line (Cat. No. 632180), the vector generates high titers of replication-incompetent, VSV-G-pseudotyped lentivirus.

Lenti-X Packaging Single Shots (VSV-G) provide an extremely simple and consistent one-step method for producing high-titer lentivirus. No additional transfection reagent is needed because Lenti-X Packaging Single Shots (VSV-G) consist of pre-aliquoted, lyophilized, single tubes of Xfect Transfection Reagent premixed with an optimized formulation of VSV-G pseudotyped Lenti-X lentiviral packaging plasmids. High-titer virus is produced by simply reconstituting this mixture with your lentiviral vector of choice in sterile water and adding it to 293T cells, e.g., Lenti-X 293T Cells (Cat. # 632180), in a 10 cm dish.

Then, the mixture was added to cultured Lenti-X 293T cells that were approximately 80% confluent. After 48 hours, titer was determined using several methods. To determine infectivity, the supernatant was harvested and used to infect HT1080 cells (Flow Cytometry). Harvested viral supernatants were also analyzed by RT-PCR to quantify viral genome copies (qRT-PCR, Lenti-X qRT-PCR Titration Kit), ELISA to measure p24 (p24 ELISA, Lenti-X p24 Rapid Titer Kit), and by a rapid lentiviral detection method (Lenti-X GoStix).

A comparison of fourth- and third-generation lentiviral packaging systems

A comparison of fourth- and third-generation lentiviral packaging systems

A comparison of fourth- and third-generation lentiviral packaging systems . Our Lenti-X Packaging single shots utilize a packaging system that consists of five separate components (Panel A), mixed in proprietary proportions for optimized packaging activity. The separation of the gag, pol, and env genes effectively reduces the incidence of RCL (Wu et al., 2000). High levels of expression of essential viral components are driven by the Tet-Off and Tat transactivators, which induce a cascade of expression that results in high titers of lentivirus. The pol gene is fused to vpr to ensure transport of the reverse transcriptase/integrase protein into the recombinant lentiviral particle. Not all vector elements are shown. Other 3rd generation lentiviral packaging systems (Panel B) generate lower titers, do not contain separate gag and pol sequences, and do not use a transactivation cascade mechanism.

The Lenti-X 293T Cell Line is a subclone of the transformed human embryonic kidney cell line, HEK 293, which is highly transfectable and supports high levels of viral protein expression. When transfected with Lenti-X Packaging Single Shots and a lentiviral vector, these cells are capable of producing lentiviral titers as high as >108 ifu/ml, as determined by flow cytometry. The cell line also constitutively expresses the simian virus 40 (SV40) large T antigen.

Clontech's lentiviral packaging system (Panel A) and a lentiviral packaging system from a leading competitor (Panel B) were each used to generate viral supernatants from their respective lentiviral system vectors that were engineered to express the ZsGreen1 fluorescent protein

Clontech's lentiviral packaging system (Panel A) and a lentiviral packaging system from a leading competitor (Panel B) were each used to generate viral supernatants from their respective lentiviral system vectors that were engineered to express the ZsGreen1 fluorescent protein
Clontech's lentiviral packaging system (Panel A) and a lentiviral packaging system from a leading competitor (Panel B) were each used to generate viral supernatants from their respective lentiviral system vectors that were engineered to express the ZsGreen1 fluorescent protein. As little as 10 µl of supernatant from Lenti-X transduced the majority of these HeLa cells, whereas 10 µl of supernatant from the other system transduced only a small percentage of the cells. Transduced cells were quantified by flow cytometry.

Transduction of neural progenitor cells by Lenti-X lentivirus

Transduction of neural progenitor cells by Lenti-X lentivirus. Recombinant lentivirus for expressing ZsGreen1 was produced using Lenti-X virus and used to transduce normal human neural progenitor cells. A single transduced cell is shown under phase contrast microscopy (Panel A) and fluorescence microscopy (Panel B).

High-titer lentivirus production

High-titer lentivirus production

High-titer lentivirus production. Lenti-X 293T cells were transduced with the indicated volumes (µl) of lentiviral packaging supernatant generated with the Lenti-X Expression System and then selected with puromycin for 9 days to allow the formation of the resistant colonies, which were then stained with crystal violet.

293T cell line for higher titers

293T cell line for higher titers

293T cell line for higher titers. We used our fourth-generation lentiviral packaging system and one of our pLVX-lentiviral vectors to compare the virus production of the Lenti-X 293T Cell Line to that of two other commonly used HEK 293-based cell lines. Lenti-X 293T cells clearly outperformed the other cell lines—producing over 6X more virus than 293FT cells and up to 30X more virus than the parental HEK 293 cell line.
