Overview

Aprotinin is a 58 amino acid-long protein, with a calculated molecular weight of 6512 Da, that acts as a serine protease inhibitor. Known also as bovine pancreatic trypsin inhibitor (BPTI), aprotinin inhibits serine proteases such as chymotrypsin, kallikrein, plasmin and trypsin. 

Application
Aprotinin is largely used as an inhibitor of trypsin.

Note
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
