The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Approximately 5000 Units/mg material.
The spectrophotometric assay to determine the activity of trypsin measures the increase in absorbance at 253 nm due to N-a-benzoyl arginine as it is cleaved from N-a-benzoyl arginine ethyl ester, with the concomitant formation of ethanol.
Trypsin catalyzes the cleavage of peptide bonds in proteins at the carboxyl side of arginine and lysine residues, except when either is followed by a proline residue. Trypsin is commonly used to remove adherent cells during cell culture manipulations carried out in vitro.

TCR V beta 4.1
Has activity against the synthetic substrates Boc-Phe-Ser-Arg-Mec, Boc-Leu-Thr-Arg-Mec, Boc-Gln-Ala-Arg-Mec and Boc-Val-Pro-Arg-Mec. The single-chain form is more active than the two-chain form against all of these substrates.
Involvement in disease
Defects in PRSS1 are a cause of hereditary pancreatitis (HPC) [MIM:167800]; also known as chronic pancreatitis (CP). HPC is an autosomal dominant disease characterized by the presence of calculi in pancreatic ducts. It causes severe abdominal pain attacks.
Belongs to the peptidase S1 family. Contains 1 peptidase S1 domain.
Occurs in a single-chain form and a two-chain form, produced by proteolytic cleavage after Arg-122.
