Animal Origin Free Chymotrypsin Enzyme for Peptide Fingerprinting
Chymotrypsin is a recombinant serine endopeptidase expressed in E.coli, purified with HPLC, the gene sequence is the same as human
chymotrypsin. Recombinant chymotrypsin hydrolyzes at the carboxyl
side of aromatic amino acids residues: Tyr, Phe and Trp. Cleavage
may also be observed, but at a lower rate, at Leu and Met.
Chymotrypsin activity is optimal in pH 7.0–9.0.
Prepare 1-10mg/ml with 1ml 50mM HAc, used within 2 days, or stored
below -20℃ after repacked
Recombinant Chymotrypsin lyophilized should be stored under 2℃-8℃in
sealed container.It is stable within 24 months. After dissolved, it
should be stored under -20℃.
