It has the advantages of simple and fast operation, high sensitivity, strong specificity, and good stability, which can minimize human error and pollution. This polymerase has 5 '-3' DNA polymerase activity, 5 '-3' exonuclease activity, and 3 '-5' exonuclease activity. Under normal PCR conditions, compared with GoldStar DNA polymerase, it has excellent performance of high amplification efficiency and low mismatch rate. The chemically modified enzyme does not exhibit polymerase activity at room temperature, effectively avoiding non-specific amplification caused by non-specific binding of primers and templates or primer dimers at room temperature. Enzyme activation requires incubation at 95 ℃ for 10 minutes, which can be integrated into existing PCR thermal cycling programs. The optimized buffer system maximizes the effectiveness of the enzyme, achieving high fidelity, specificity, amplification efficiency, and sensitivity for the target fragment. This product does not contain dyes. After the PCR program is completed, an appropriate amount of sample buffer can be added as needed for electrophoresis operation. Most PCR products obtained from amplification have an "A" base attached to the 3 'end, making them suitable for direct use in T/A cloning. Suitable for routine PCR reactions and gene cloning experiments that require high fidelity.Note: 2 x GoldStar Best MasterMix contains GoldStar Best DNAPolymerase, 3.4 mM MgCl2, and 400 µ M each dNTP.G665561Component1 mL5 mL25 mLStorageG665561A2×GoldStar Best MasterMix1 mL5×1 mL5×5 mL-20℃.Avoid freeze/thaw cycle.

Notice: 2×GoldStar Best MasterMix contains GoldStar Best DNA Polymerase, 3.4 mM MgCl2 and 400 µM each dNTP.Quality control:After testing, there was no exogenous nuclease activity; PCR method for detecting residual DNA without host; Can effectively amplify single copy genes from multiple genomes; Storage at 2-8 ℃ for three months showed no significant change in activity.Usage:The following is an example of a PCR reaction system and reaction conditions for amplifying a 1 kb fragment using human genomic DNA as a template. In practical operation, corresponding improvements and optimizations should be made based on the template, primer structure, and target fragment size.1.

In the case of low amplification efficiency, the concentration of primers can be increased; When non-specific reactions occur, the primer concentration can be reduced to optimize the reaction system.2.

The amplification efficiency of GoldStar Best DNA Polymerase contained in this product is 1-2 kb/min.3) The number of cycles can be set based on the downstream application of the amplification product. If the number of cycles is too small, the amplification amount is insufficient; If there are too many cycles, the probability of mismatches will increase, and non-specific backgrounds will be severe. So, while ensuring product yield, the number of cycles should be minimized as much as possible.4) This product must achieve enzyme activation under pre denaturation conditions of 95 ℃ and 10 minutes...
