Adjusted Vmax* (RFU/min) x Conversion Factor** (pmol/RFU)
amount of enzyme (µg)

     *Adjusted for Substrate Blank

     **Derived using calibration standard MCA-Pro-Leu-OH (Bachem, Catalog # M-1975).

Per Well:
  • rhTrypsin 2: 0.0025
  • Substrate: 10 μM

Human Trypsin 2, encoded by the PRSS2 gene, is also known as anionic Trypsin (1). Accounting for approximately 1/3 of the total trypsin content in the pancreatic juice, it is one of the trypsins produced in the pancreas. It consists of a signal peptide (residues 1‑15), a pro region (residues 16‑23), and a mature chain (residues 24‑247). Trypsin 2 is synthesized as a zymogen and secreted into the duodenal lumen, where it is activated by enteropeptidase (2). It plays a central role in digestion and activating other pro-enzymes. In human pancreatic diseases and chronic alcoholism, it is up-regulated (3).
