Blog O Genscript Launches Stable PCR Kit to Enhance Lab Productivity

Laboratory researchers can now say goodbye to the time-consuming process of thawing PCR reagents and concerns about enzyme activity degradation from repeated freeze-thaw cycles. A groundbreaking high-stability PCR kit has been developed to transform experimental workflows and enhance research efficiency.

The new PCR kit eliminates the need for last-minute reagent thawing, allowing researchers to begin experiments immediately. Through proprietary technology, the kit combines Green Taq DNA polymerase, 10× Taq buffer, and stabilized dNTPs in a formulation that delivers exceptional stability.

This innovation enables storage at 4°C for over six months or at room temperature (25°C) for one month with minimal activity loss. The temperature-resistant properties allow for on-demand experimentation without reagent degradation concerns, significantly simplifying lab management while improving reliability - particularly beneficial for high-throughput PCR applications requiring rapid turnaround.

For experiments requiring long DNA fragment amplification, the stability and activity of DNA polymerase are critical. The kit's Green Taq DNA polymerase incorporates specialized stabilizers that maintain enzymatic activity during storage while significantly improving high-temperature (72°C) stability during PCR cycles.

This extended enzyme half-life translates directly to higher DNA yields, particularly in challenging long-fragment amplifications where conventional polymerases often underperform. The modified enzyme retains Taq DNA polymerase's characteristic terminal transferase activity, adding an extra adenosine at the 3' end of extension products - a feature potentially valuable for certain downstream applications.

The cornerstone of the kit, this modified enzyme delivers superior thermal stability and extended half-life, enabling high-yield PCR - especially for long fragment amplification.

Contains 500 mM KCl, 100 mM Tris HCl (pH 9.0 at 25°C), 15 mM MgCl₂, 1% Triton X-100, and critical stabilizers. This optimized formulation creates ideal reaction conditions while enhancing enzyme stability at elevated temperatures.

These DNA synthesis building blocks undergo stabilization treatment to prevent degradation during storage and use, ensuring consistent PCR efficiency and accuracy.

Experimental data demonstrates the kit's superior capabilities. In one test, the Green Taq DNA polymerase successfully amplified an 8-kb λDNA fragment with three-minute extension times, significantly outperforming standard Taq polymerase in yield.

Additional stability testing showed minimal activity loss after 14 days at 37°C, with successful amplification of a 2-kb 23S rRNA fragment from E. coli genomic DNA - confirming reliability across various storage conditions.

The PCR system offers both complete kits and individual component purchasing options:

• Green Taq DNA Polymerase: 100 μl (500 U)
• 10× Taq Buffer (with Mg²⁺): 1.5 ml
• Stabilized dNTP Mix: 300 μl (10 mM each)

This high-stability PCR kit represents a significant advancement in molecular biology tools, offering researchers unprecedented convenience and reliability for both routine and challenging amplification tasks. Its temperature-resistant properties and sustained enzymatic activity make it particularly valuable for accelerating research timelines and improving experimental outcomes.
