General description

REDTaq Genomic DNA Polymerase is a unique blend of Taq DNA Polymerase with an inert red dye. This special formulation is designed to provide enhanced amplification of more complex or genomic templates. REDTaq Genomic DNA Polymerase is highly sensitive, produces increased yields and is capable of generating longer product lengths. It has all the advantages of REDTaq DNA polymerase, such as easy visualization of enzyme addition and complete reaction mixing, and direct loading to an agarose gel. The dye migrates slightly faster than bromophenol blue at approximately the same rate as a 125 base pair fragment.
The inert red dye does not effect automated or manual sequencing, restriction digestions or other downstream applications. The dye can easily removed by any standard purification method.

The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides (the building blocks of DNA). These enzymes are essential for DNA replication and usually work in pairs. It creates two identical DNA strands from a single original DNA molecule. During this process, DNA polymerase “reads” the existing DNA strands to create two new strands that match the existing ones.


REDTaq® Genomic DNA Polymerase is used for routine PCR amplification from genomic DNA.

Features and Benefits

• Enhanced amplification on genomic and difficult DNA templates
• Same great performance as Taq DNA Polymerase in a more convenient format for high throughput applications
• Quick recognition and confirmation of appropriate mixing
• No loading buffers or tracking dyes necessary. Sample can be taken directly from reaction and loaded onto an agarose gel


Includes 10× PCR Reaction Buffer

Unit Definition

One unit incorporates 10 nmol of total dNTPs into acid precipitable DNA in 30 min. at 74°C.
