Hieff Unicon™ Robust Hotstart Taq DNA Polymerase, Glycerol-free (20 U/μL) _ 14331ES

Hieff Unicon™ Robust Hotstart Taq DNA Polymerase, Glycerol-free (20 U/μL) is an antibody-mediated hot-start DNA polymerase with high amplification sensitivity and specificity. The blocking antibody is fully inactivated within 30 seconds at the initial denaturation temperature, releasing DNA polymerase activity. This hot-start mechanism helps suppress amplification caused by nonspecific primer annealing. The glycerol-free formulation is designed specifically for preparing lyophilized reagents. Features Lyophilization-Ready: Glycerol-free liquid formulation optimized for lyophilized reagent production. High Inhibitor Tolerance: Compatible with complex samples (swabs, blood); lyophilized beads support full-volume reconstitution with nucleic acid extracts. High Performance: Antibody-mediated hot-start ensures sensitive and specific amplification. Robust Stability: Retains >90% activity after 7 days at 37°C or 20 freeze-thaw cycles.

Strong Stability Two batches of 14331 were evaluated for accelerated thermal stability and repeated freeze–thaw stability, with material stored at -20℃ as the control. After 7 days at 37℃ or 20 freeze–thaw cycles, both batches retained more than 90% of the activity measured under standard storage conditions. Figure 1.

African Swine Fever Virus Detection with Lyophilized Beads Item Content Reagents 14331 was combined with qPCR buffer, ASFV primers/probes, and lyoprotectants to prepare 25 μL lyophilized qPCR reagents Samples Eight farm whole-blood samples were extracted by magnetic beads; 400 μL input, 70 μL elution Testing Lyophilized reactions were reconstituted with 5 μL or 25 μL nucleic acid extract, topped up to 25 μL with water Results 25 μL reconstitution gave Ct values ~2–4 cycles earlier than 5 μL, indicating tolerance to higher extract input and improved sensitivity Table 1.
