产品信息

Bst 2.0 DNA Polymerase |

Bst 2.0 DNA Polymerase is an in silico designed homologue of Bacillus stearothermophilus DNA Polymerase I, Large Fragment (Bst DNA Polymerase, Large Fragment). Bst 2.0 DNA Polymerase contains 5´→3´ DNA polymerase activity and strong strand displacement activity but lacks 5´→3´ exonuclease activity. Bst 2.0 DNA Polymerase displays improved amplification speed, yield, salt tolerance and thermostability compared to wild-type Bst DNA Polymerase, Large Fragment.

LAMP Salt Tolerance Bst 2.0 DNA Polymerase |
Performing LAMP reactions with increasing amounts of salt demonstrate increased resistance to inhibitors by using Bst 2.0. Bst 2.0 maintains high levels of activity where wild-type Bst DNA polymerase, large fragment, is completely inhibited.
Rapid LAMP Detection Bst 2.0 DNA Polymerase |
LAMP reactions amplifying different targets demonstrate a more rapid amplification threshold time using Bst 2.0 vs. Bst, large fragment.

产品来源

Bst 2.0 DNA Polymerase is prepared from an E. coli strain that expresses the Bst 2.0 DNA Polymerase protein from an inducible promoter.
