ExtraLong Taq DNA Polymerase, a high fidelity of polymerases with 3’-5’ exonuclease activity designed for amplifying large fragment. A wide range of PCR products can be generated, up to 40 kb from lambda DNA and 30 kb from human genomic DNA. It is also a better choice for amplifying complex template, such as GC-rich template. ExtraLong Taq Polymerase is suitable as a direct replacement for ordinary Taq Polymerase in most applications. PCR products produced with ExtraLong Taq Polymerase can be used in either TA cloning or blunt cloning
