B-Bridge's Taq DNA Polymerase Pre-Mix is a ready-to-use 1.1X reaction mix. Simply add primers, template, and water to successfully carry out primer extensions and other molecular biology applications. B-Bridge Taq DNA Polymerase, the NH4+ buffer system, dNTPs, and magnesium chloride are present in Taq DNA Polymerase Mix. Each reaction requires 45 uL of the 1.1X reaction mix. Simply add primers, template and water to a total reaction volume of 50 uL.Taq DNA Polymerase Pre-Mix offers several advantages. Set up time is significantly reduced. The chance of contaminating component stocks is eliminated. Reduction of reagent handling steps leads to better reproducibility. Standard tests can be set up with the confidence that results will be consistent every time.
