Taq PCR Buffer, 5x

Taq PCR Buffer, 5x is a novel buffer system that has been designed to be combined with a high quality Taq DNA polymerase such as MDX001 or MDX008, to deliver very high yield PCR amplification over a wide range of PCR templates and has been developed to give very robust amplification allowing it to perform well with challenging templates in the presence of PCR inhibitors.

Robust PCR amplification of GC-rich human genomic DNA

Taq DNA Polymerase graph
A serial dilution in duplicate of human genomic DNA (1 μg, 200 ng, 100 ng, 50 ng, 25 ng and 12.5 ng, 1-6 respectively) was used with primers and Taq DNA Polymerase to amplify a 450 bp fragment of the human myc gene. The section of gene used has 61% GC content and was selected to demonstrate the high yield and sensitivity of the Taq DNA Polymerase, making it the perfect choice for the amplification of complex PCR templates.

FAQs: Taq DNA Buffer

Taq DNA Buffer has been validated for use with a broad range of PCR templates including DNA extracted from human, animal and plant samples, making it the ideal choice for the following applications:
• End-point PCR testing
• High-yield PCR testing
• Fast PCR testing
• Multiplex PCR testing

For qPCR we recommend the use of Fast qPCR Buffer, 4x (MDX033) as it has been optimized for this application.

This depends on the polymerase used as well as the length of the amplicon and the complexity of the template. For fast PCR, with Taq HS DNA polymerase (MDX008), the initial denaturation is 1 minute, but with low complexity template such as plasmid DNA, an annealing of 5 seconds and extension time of 10 seconds is sufficient for amplicons up to 1 kb. In order to find the fastest optimal condition, for more complex or longer amplicons, we suggest incrementally increasing the extension time successively up to 30 s/kb.

Decreasing the template concentration will help to minimize the concentration of inhibitors, the amount of DNA polymerase and primer can also be increased. In some cases, you may also have to add a pre-treatment step if the DNA is not accessible.
