||HotStart Taq DNA polymerase is an innovative antibody-modified thermostable enzyme. The activity of the enzyme is completely closed at room temperature, avoiding the non-specific amplification and primer dimer in the preparation of the sample and the first cycle reaction temperature rise, increasing the specificity of DNA amplification. HotStart Taq 2x Master Mix is an optimized ready-to-use solution containing HotStart Taq DNA Polymerase, dNTPs, MgCl2, KCI and stabilizers. It is ideally suited to routine PCR applications from templates including pure DNA solutions, bacterial colonies, and cDNA products. It can amplify up to 4 kb from complex genomic DNA or up to 5 kb from lambda DNA. Applicable to the PCR reaction, colony PCR, primer extension, etc.
