Detailed Description

Trypsin is a member of the serine protease family. Trypsin cleaves peptides on the C-terminal end of lysine and arginine amino acid residues. The pH optimum of trypsin is pH 7 - 10. The enzyme is inhibited by serine protease inhibitors, e.g. PMSF, and by metal chelating agents, e.g., EDTA. Recombinant Trypsin is a genetically engineered protein expressed in E.coli and purified by high pressure liquid chromatography. There is no trace of contaminating enzyme activities such as from carboxypeptidase A and chymotrypsin. No protease inhibitors such as PMSF are contained in the preparation. ADVANTAGES ● Animal origin free The use of recombinant Trypsin eliminates the risk of virus presence, and other potential adventitious agents found in animal-derived trypsin. YaxinBio Recombinant Trypsin belongs to the AOF level 3. ● Stable A sterile recombinant trypsin lyophilized powder eliminates the contamination risks and decreases the chance of activity loss in the process of transport and storage. ● High purity 1) Recombinant trypsin provides increased specificity and eliminates contaminating activities found in enzymes with lower purity level. 2) No other contaminating proteases such as chymotrypsin or carboxypeptidase A. 3) One single main band at 24kD by SDS-PAGE. MAIN FEATURES Source E. Coli Purified by HPLC Physical form White lyophilized powder Additives Carbohydrates Protein content 35% ~ 50% Specific activity >3000 USP units/mg pro. Purity > 95% Contaminant activity No chymotrypsin, carboxypeptidase A, or other protease contaminant.
