1.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. YaxinBio recombinant trypsin is a genetically engineered protein expressed in E.coli and the amino acid sequence of recombinant trypsin is identical to porcine pancreas-derived trypsin,with equivalent properties compared to native trypsin .Recombinant trypsin can replace native trypsin for using in a variety of biotechnological processes. The M.W. of recombinant trypsin is 24KD,and the optimum pH is pH 7.0-11.0. The enzyme is inhibited by serine protease inhibitors, e.g. PMSF,soybean trypsin inhibitor and by metal chelating agents, e.g.EDTA.

3.RECOMMEND USAGE
Prepare 1-10mg/ml recombinant trypsin with 1mM HCl.The ratio to aimed protein is 1:50 to 1:1000 (w/w).The optimum pH is pH7.0-11.0.

4.STABILITY OF STORAGE AND TRANSPORT
Stability of storage: Recombinant trypsin lyophilized should be stored under 2-8℃ in sealed container. It is stable within 24 months.After dissolved with 1mM HCl or 50mM HAC, it should be stored under -20℃. It is no activity loss after 10 times repeated freezing and thawing.
Stability of transport: The product is stable by blue ice insulation transport.

5.PRODUCT ADVANTAGE
Animal origin free: recombinant trypsin is no exogenous virus contamination,and any animal origin material is not used in the production process.
Stable quality: Mass production can ensure stable and continuous batch production.It is no difference between the batch and the product quality is stable.
