Taq PCR Master Mix with Dye

Taq PCR Master Mix with Dye includes premixed loading dye and 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 is premixed with DNA loading dye allowing for quick agarose gel loading of PCR products following PCR reactions.

Quality Control

The quality of  Taq PCR Master Mix is tested on a lot-to-lot basis according to Geneaid's ISO-certified quality management system. Taq PCR Master Mix is used for PCR reactions to amplify a 3,000 bp region of the green fluorescent protein gene (GFP). The PCR product is checked on an ethidium bromide-stained agarose gel.
