KAPA Taq is supplied in a 2X ReadyMix™ format. It comprises all the components required for PCR except primers and template. Simply use PCR-grade water to make up the required reaction volume. KAPA Taq DNA Polymerase comprises two reaction buffers (Buffer A and Buffer B) or a single buffer with loading dye. It aids convenient direct analysis of the PCR product by agarose gel electrophoresis after cycling. KAPA Taq Buffer A (and KAPA Taq Buffer with dye) are standard Tris-ammonium sulfate-based buffers. KAPA Taq Buffer B is a Tris-potassium chloride buffer. KAPA Taq DNA Polymerase combines with any standard Taq buffer with a pH of 8.3 or higher.
