Trypsin

• CAT Number: I042947
• CAS Number: 9002-07-7
• Purity: ≥95%

Trypsin is a serine protease enzyme, and hydrolyzes proteins at the carboxyl side of the Lysine or Arginine. Trypsin activates PAR2 and PAR4. Trypsin induces cell-to-cell membrane fusion in PDCoV infection by the interaction of S glycoprotein of PDCoV and pAPN. Trypsin also promotes cell proliferation and differentiation. Trypsin can be used in the research of wound healing and neurogenic inflammation[1][2][3][4][6].
Trypsin (5 μg/mL, 24 or 48 h) promotes porcine deltacoronavirus (PDCoV) replication in LLC-PK cells[2].
Trypsin (10 and 50 ng/mL, 12 h) enhances PDCoV cell-to-cell spread in LLC-PK cells by promoting membrane fusion in LLC-PK cells[2].
Trypsin (0.05%, 3 h) promotes C6 glioma cell proliferation in serum-free and growth factor-free medium[3].
Trypsin (20 -150 ng/mL, 5 days) potentiates PBMC differentiation[4].
Trypsin (100-500 μg per site in 50 μL saline, intradermal injection) induces scratching behaviour in mice[5].
