KAPA Mouse Genotyping Kits include KAPA Express Extract, a novel thermostable protease and buffer system that allows for the extraction of PCR-ready DNA from mouse tissue in as little as 15 minutes. The kit also includes KAPA2G Fast Genotyping Mix with dye containing a DNA polymerase engineered via our directed evolution technology for high processivity and extreme speed. The combination of KAPA Express Extract and KAPA2G Fast Genotyping Mix allows for the reliable extraction and amplification of DNA fragments from mouse tissue in as little as 1 hour compared to ≥1 day with conventional protocols.
