Advantage Genomic LA Polymerase Mix and Advantage GC Genomic LA Polymerase Mix are designed for long and accurate (LA) PCR amplification. These mixes offer 6.5X higher fidelity than wild-type Taq DNA polymerase, and allow synthesis of products up to 30 kb for complex templates such as genomic DNA, and up to 48 kb for less complex templates such as λ DNA. Both versions of Advantage Genomic GC Polymerase Mix are composed of a full-length Taq DNA polymerase, a small amount of proofreading enzyme, and a hot-start antibody, and are supplied with optimized buffers.
