Product Introduction

Taq DNA polymerase is a recombinant, heat-resistant DNA polymerase. It was named Taq polymerase because it was discovered in the thermophilic aquatic bacterium Thermus aquaticus in hot springs. It has 5'-3' polymerase activity and 5'-3' exonuclease activity.

Product Feature

- High purity: purity >95%, no residual nuclease, low residual host gDNA;

- Good compatibility: compatible with multiple Buffers, active at pH 8.3-11.6;

- High sensitivity: improved template affinity through modification, increasing the detection sensitivity of low concentration templates;

- Good specificity: electrophoresis detection of target band is single, no tailing;

Product Application

- Routine PCR amplification


- Fluorescent quantitative PCR

- Product can be directly TA cloned

Figure 3. qPCR was performed on plasmid templates with different copy numbers of 5000, 500, 50, and 5 copies using CSB-DEM023 Taq DNA Polymerase and similar products. It can be seen that CSB-DEM023 Taq DNA Polymerase has excellent linearity and amplification efficiency in the lower template concentration range.
