This product is a type II restriction endonuclease derived from the recombinant protein encoded by the BspQI gene in Bacillus sphaericus expressed by E.coli. Its recognition sequence is 5'-GCTCTTCN1/N4-3'. Use to digest plasmids to prepare poly(A/T/G/C)-terminated linearized DNA fragments to obtain specific cohesive ends.
This product is produced in accordance with GMP process requirements and provided in a liquid form.
