CAS Registry Number

CAS 9087-70-1 — Aprotinin

Aprotinin is a serine protease inhibitor derived from bovine lungs, widely used in medical and research applications to prevent excessive proteolysis, particularly in cardiopulmonary bypass surgeries and experimental settings. It is a polypeptide with high affinity for trypsin, kallikrein, and plasmin, helping preserve protein integrity in biological systems. Catalogue details: CAS 9087-70-1, molecular formula C284H432N84O79S7, molecular weight 6511.45 g/mol, requires storage at 2–8°C, and carries a **Danger** signal word due to potential health hazards. Molekula supplies Aprotinin from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

Also known as: Aprotinin – Recombinant, expressed in E. Coli
