General description

Trypsin is a serine protease that specifically hydrolyzes peptide bonds at the carboxyl side of lysine and arginine residues. This modified trypsin has been treated with N-tosyl-L-phenylalanine chloromethyl ketone (TPCK) to inactivate extraneous chymotryptic activity. Each package contains 8 vials, with 25 μg in each vial.

Application

Trypsin, TPCK-Treated has been used:
  • as a supplement in Dulbecco′s Modified Eagle Medium (DMEM) for porcine delta coronavirus (PDCoV) infection experiments using epithelial-like pig kidney cell line (LLC-PK1)
  • to detach the human umbilical vein endothelial cells (HUVEC) for annexin-V/propidium Iodide (PI) staining assay
  • in minimum essential medium (MEM) for multicycle replication kinetics

Biochem/physiol Actions

N-p-Tosyl-L-phenylalanine chloromethyl ketone (TPCK) serves as an irreversible inhibitor of chymotrypsin. Trypsin induces human fibrocyte differentiation. Trypsin is widely used in proteomics for protein sample digestion. In cell culture, trypsinization is carried out to dislodge adherent cells from each other and the walls of the culture vessel.

Trypsin-containing topical treatments can be used to speed wound healing, although the mechanism of action is unknown. To help form granulation tissue and heal wounds, monocytes leave the circulation, enter the wound tissue, and differentiate into fibroblast-like cells called fibrocytes.

Trypsin is the protease of choice for protein sample digestion in proteomics. The most typical active forms are the single-chain β-trypsin and the two-chain α-trypsin, which is produced by a limited autolysis of β-trypsin. An additional intra-chain split leads to
