The product is a hot start DNA polymerase with double blocking by double antibodies independently developed by the company. This product not only blocks the 5'→3' polymerase activity of Taq DNA polymerase, but also blocks the 5'→3' exonuclease activity. Heating for 30 seconds at the pre denaturation temperature can completely inactivate the antibody and release DNA polymerase activity and exonuclease activity. The double blocking characteristic can not only effectively prevent the nonspecific amplification caused by mismatch or primer dimer, but also effectively inhibit the decline of fluorescence signal caused by probe degradation, so as to make the in vitro detection reagent more stable during transportation or use at room temperature.
In addition, this product has been processed with the UCF.ME™ ultra-low residual process from Yeasen Biotechnology, resulting in extremely low residual levels of nucleases and host gDNA. With an optimized amplification buffer (e.g., Cat#16716ES), it can effectively reduce non-specific amplification caused by primer-probe hybridization during sample mixing, system warming, and long-term storage. This supports the development of a real time PCR system that allows for pre-mixing of primers and probes.
Features
- Low nuclease residue: No residual exonuclease, nicking enzyme, or RNase.
- Ultra-low Residual: E. coli DNA residue level < 0.02 copies/100 U, suitable for applications with more stringent background bacterial requirements.
- Super stability: All components of the qPCR system except the template were combined and incubated at 37 °C for 7 days without compromising performance.
- Batch-to-batch stability: The UCF.ME™ ultra-clean molecular enzyme production platform, with strict quality control, ensures the uniformity, stability, and timely supply of the product.

Store this enzyme at -20°C and avoid repeated freeze-thaw cycles to preserve catalytic activity. The product is shipped Dry Ice and remains stable for up to one year from the date of manufacture when stored under recommended conditions. Aliquoting the stock solution into single-use volumes is recommended for enzymes used infrequently to minimize thermal cycling of the bulk stock.
This enzyme is validated for use in PCR & Amplification, Molecular Diagnostics applications. It is suitable for use in both standard laboratory research settings and, where applicable, optimized reaction workflows requiring high specificity, sensitivity, or throughput.
One unit (U) is defined as the amount of enzyme required to incorporate 10 nmol of deoxyribonucleotide in 30 min at 74°C. The Hot Start format employs monoclonal antibody or chemical modification to inhibit polymerase activity below the denaturation temperature.
This enzyme is produced as Recombinant (E. coli) and supplied as a Research Use Only (RUO) reagent. Each lot is subjected to activity assay, purity assessment by SDS-PAGE, and functional validation prior to release. A Certificate of Analysis (CoA) and Safety Data Sheet (SDS) are available on request.
Hot Start formulations use monoclonal antibodies or chemical modification to block polymerase activity at room temperature, preventing non-specific extension during reaction setup. Full activity is restored after initial denaturation (≥95°C). This results in reduced primer-dimer formation, suppression of non-specific amplification products, and improved sensitivity in complex or low-abundance templates.
