Bst DNA Polymerase, Large Fragment is moderately thermostable enzyme from Bacillus stearothermophilus cloned to E. coli. It exhibits thermophilic reverse transcriptase activity and is active over a wide range of reaction buffer conditions and magnesium ion concentrations. This polymerase shows a strong strand displacement capabilities making it an ideal candidate for isothermal amplification (LAMP), whole genome amplification (WGA), and multiple displacement amplification (MDA).
Bst DNA Polymerase, exonuclease minus, is a 67 kDa Bacillus stearothermophilus DNA Polymerase protein with a 5'-3' polymerase activity, strand displacement activity, and reverse transcription activity. There is no detectable 3'-5' exonuclease activity. The concentration is 10 U/ul.
Isothermal DNA amplification, LAMP, DNA strand displacement amplification, whole genome amplification, sequencing of DNA with high CG content and problematic secondary structures, rapid sequencing and amplification from very low amounts of DNA templates (10 fg). LAMP assay: 2,5 ul 10x BST Buffer, 0,8 ul MgSO4 (25 mM), dNTPs (10 mM), 4 ul Betaine (5M), 1,6 ul mecA FIP primer (10 mM), 1,6 ul mecA BIP primer (10 mM), 0,2 ul mecA F3 primer (10 mM), 0,2 ul mecA B3 primer (10 mM), 0.1 mg/ml BSA, 1 ul BST polymerase, 1 ul template DNA, 10,5 ul H2O.
