KAPA Library Amplification Kits include KAPA HiFi DNA Polymerase, a novel enzyme engineered using our directed evolution technology for ultra-high fidelity and robustness. KAPA HiFi has become the enzyme of choice for next-generation sequencing (NGS) library amplification due to its ability to amplify complex DNA populations with high fidelity, high efficiency and very low amplification bias. This results in lower duplication rates and improved coverage of GC- and AT-nch regions, promoters, low-complexity and other challenging regions.
