Bst L DNA polymerase is a homology of Bacillus Stearothermophilus DNA polymerase I, large fragment (Bst DNA polymerase, large fragment) and was designed by computer simulation. Bst L DNA polymerase has 5´→3´ polymerase activity and strong chain substitution activity, but does not have 5´→3´ exonuclease activity. Compared with wild-type Bst DNA polymerase, the enzyme can effectively increase the amplification speed, yield, salt tolerance and thermal stability, etc.
Store Buffer: 10 mM Tris-HCl pH 7.1，50 mM KCl，0.1 mM EDTA，1 mM DTT，0.1% Triton X-100，50% Glycerin
Storage Conditions
Transport in ice packs, store at -20℃. Avoid repeated freezing and thawing. The product is valid for 1 years.
Unit Definition
One unit is defined as the amount of enzyme that will incorporate 25 nmol of dNTP into acid insoluble material in 30 minutes at 65°C.
Quality Control
Endonuclease residue detection: The 50 μL reaction system added 500 U enzyme, 1 μg of PUC19 DNA vector, and incubated at 37℃ for 4 hours without degradation signal.
Exonuclease residue detection: After incubation at 37℃ for 16 h, the electrophoretic bands of DNA did not change after adding 500 U enzyme and 1 μg Lambda-Hind III DNA into the reaction system.
RNase residue detection RNase: 8 U enzyme and 40 ng RNA (3500 nt) were incubated at 37℃ for 16 h, and the electrophoresis band of RNA did not change.
E .Coli DNA residue detection: The remaining nucleic acid in 120 U of this enzyme was detected by TaqMan qPCR for E. coli gDNA, and the E. coli genome residue was less than 1 copies.
Experiment Process
1.Take out 10×Bst L Buffer, thaw on ice, vortex for 10 seconds before use. Mix well and collect by centrifugation briefly.
2.In addition to the template DNA, the remaining components are configured in the order shown in the table below
3.Mix by pipetting, and centrifuge briefly to collect.
4.Constant temperature incubation at 60°C-65°C for 1 hour
Precaution
- The Bst L Buffer can be dissolved at room temperature. After dissolution, it should be stored in an ice box or ice bath. After using, it should be stored at -20℃ immediately.
- For your safety and health, please wear lab coat and disposable gloves.
1) Isothermal amplification.
2) DNA sequencing with high GC content
