LA Taq DNA polymerase, hot-start version
TaKaRa LA Taq DNA Polymerase Hot-Start Version consists of Takara LA Taq polymerase plus a monoclonal antibody. The antibody binds Taq polymerase, thereby preventing nonspecific amplification due to mispriming and/or formation of primer dimers during PCR assembly. This hot-start version of LA Taq retains all of the high-performance features of Takara LA Taq polymerase while increasing reaction specificity and reducing background. An optimized LA PCR Buffer II (Mg2+) and dNTP mixture are supplied with the polymerase.

For hot-start long-range PCR of targets with high GC content in high-fidelity applications, we recommend using PrimeSTAR GXL DNA Polymerase (Cat. # R050A).
Use our LA PCR Genome DNA Set as your long-range PCR experimental controls. The set includes purified, high-molecular-weight human and E. coli genomic DNA plus appropriate primers.
For non-hot-start options, visit our LA Taq DNA polymerase page to learn about the different formulations we offer.
Overview
- Robust amplification of long DNA templates (long-range PCR)
- Integrated antibody-mediated hot-start PCR—reduces non-sepcific background amplification and increases reaction specificity
- Specially optimized buffer (LA Buffer II)—less optimization is required and gives greater yield
- DNA proofreading polymerase mix—offers higher fidelity compared with conventional Taq DNA polymerase

Applications
- Long-range PCR to amplify long amplicons
- Amplification of highly homologous sequences
- Pseudogene identification
- Mitochondrial DNA sequencing
PCR products
PCR products generated with Takara LA Taq contain a mixture of 3'-A overhangs and blunt ends, allowing >80% cloning efficiency into T-vectors. However, the efficiency of cloning longer products (>5 kb) into T-vectors is quite low.

"It works very well for long pcr and easy optimise conditions. I have used it extensively in amplifiying 4kb to 17kb."
—Praveen Hajeri, UNIVERSITY OF MINNESOTA
"I have purchased your LA Taq. I tried it with and without adding pfu. I was looking for more product per PCR reaction. I got ~2X the amount vs my old Taq in a side by side test. Thanks "
—Maureen Tarsio, RESEARCH FOUNDATION FOR THE STATE UNIVERSITY OF NEW YORK
