Sequencing grade modified trypsin used for Peptide fingerprinting analysis

Sequencing Grade Trypsin / SRT / sequencing grade enzyme


CAS: 9002-07-7



SOURCE:Expressed in E. Coli, purified by HPLC.



Sequencing Grade Trypsin

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 Porcine 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
