Restriction enzymes are a class of endonucleases that recognize specific deoxynucleotide sequences and cleave phosphodiester bonds between two deoxyribonucleotides at specific sites in each strand. Restriction enzymes are important components of the "restriction-modification system". The biological role is to protect the host from foreign DNA infection. XbaI, derived from Xanthomonas campestris, is a commonly used type II restriction enzyme. This product is obtained by recombinant protein production technology, using pharmaceutical specifications of raw materials production, and strict control of bacterial endotoxin, nucleic acid residues. We guarantee the manufacturing and quality control comply with GMP regulation for tracking each and every step of the manufacturing process, including raw material sourcing.
