BsaI Restriction Endonuclease


Package: 50μL, 250μL, 1ml,10ml, 100ml

Product Detail


The BsaI restriction enzyme is a type II restriction endonuclease derived from the recombinant protein encoded by the BspQI gene in Bacillus sphaericus expressed by E.coli. Restriction endonucleases are widely used in gene mapping, cloning and other fields. This enzyme rapidly cuts DNA for efficient gene linearization Bsa I , an IIs restriction endonuclease restriction endonuclease, is derived from a recombinant E. coli strain that carries the cloned and modified BsaI gene from Bacillus stearothermophilus. which have the same specificity as native enzymes and reduced star activity. Its recognition sequence and cleavage sites are as follows:

Chemical Structure


Product features

• The restriction endonuclease has high enzymatic activity and completes digestion reaction quickly.

• Low non-specific endonuclease activity to ensure precise "scalpel" cutting.

• No BSA system, reducing heat source pollution.
