The LA PCR Kit, Version 2.1 contains all the reagents needed for amplification of long DNA templates, enabling routine amplification of products up to 20 kb in length, including GC-rich amplicons. For some DNA templates, amplification of up to 48 kb is possible. This long-range PCR kit contains TaKaRa LA Taq DNA Polymerase, buffers, MgCl2, dNTPs, molecular weight markers, and control templates, plus corresponding primers to ensure optimal PCR performance during long PCR.
