Description
Restriction endonucleases are a class of endonuclease that recognize specific deoxynucleotide sequences and cleave the phosphodiester bond between two deoxyribonucleotides at specific sites in each chain. BsaI derived from Bacillus Thermophilus, is a commonly used restriction endonuclease. BsaI recognizes the following sequence:
5’…GGTCTC(N)1↓…3’;
3’…CCAGAG(N)5↑…5’.
Then it functions DNA cleavage.
This product uses recombinant protein production technology to obtain restriction endonuclease BsaI. Applying pharmaceutical leveled adjuvant and material for production, strictly controlling host protein residues, nucleic acid residues and other impurities, we guarantee manufacture and quality control practice complying to GMP regulation, as well as all the materials traceable.
