Multipurpose SNP Genotyping qPCR MIX is a 2 × premixed reagent designed for real-time PCR of probe-based SNP genotyping, including Taq DNA Polymerase, PCR Buffer, dNTPs, Mg²⁺, enhancers and stabilizers. It is simple and convenient to operate. The unique PCR buffer system has strong tolerance to complex templates such as blood and saliva, which can not only efficiently amplify the extracted DNA, but also support the direct amplification of oral swab fluid and blood with a final concentration of no more than 15%. The samples do not require complicated extraction and storage processes. The results are rapid and accurate.
