Taq PCR Master Mix includes all of the necessary components (with the exception of template and primer) to perform PCR. Taq DNA polymerase, dNTPs, MgCl2 and reaction buffers are provided at optimized concentrations. Simply add primers, template DNA and sterile water to a final volume of up to 100 µl to complete the PCR reaction mix in routine PCR assays including colony PCR and recombinant screening PCR. Taq PCR Master Mix can be stored at 4ºC for up to 1 year which eliminates thawing time for even faster PCR.
