rTaq is a modified form of the Taq DNA polymerase enzyme that is commonly used in molecular biology applications, particularly in the polymerase chain reaction (PCR) technique. The "r" in rTaq stands for "recombinant," indicating that it is produced using recombinant DNA technology. This modified enzyme exhibits improved stability at higher temperatures compared to the native Taq polymerase, allowing for more efficient DNA amplification in PCR reactions. rTaq is widely utilized in various research and diagnostic settings due to its robust performance, high fidelity, and versatility in amplifying target DNA sequences.

Product Details FAQ Specification Instructions

This product is a heat-resistant DNA polymerase with a molecular weight of 94 kDa. It has undergone specific mutagenesis to reduce its dependence on activators and enhance amplification efficiency. It is particularly suitable for DNA amplification of fragments smaller than 6 kb, DNA labeling, DNA sequencing, etc. This polymerase possesses 5’→3’ exonuclease activity but lacks 3’→5’ exonuclease activity. The amplification products have a 3’-dA overhang, making them directly usable for TA cloning.


Low Host gDNA Residue: Unique purification process, purity >95%, with no nucleases remaining.

High Sensitivity: Detection sensitivity can reach 1ng.

Wide Template Range: Suitable for amplifying templates of different lengths up to 6kb.

Consistent Batch Quality: Stringent production processes and quality control standards result in minimal batch-to-batch variation.
