Aprotinin

Aprotinin

Aprotinin is a natural proteinase inhibitor polypeptide consisting of fifty-eight amino acids {C 284 H 432 N 84 O 79 S 7} arranged in a single polypeptide chain, cross-linked by three disulfide bridges and having a molecular mass of 6512.

Accession Number

P00974

Activity

6,300 KIU (Kallikrein Inactivator Units) per mg, 4.85 TIU/mg.

Formulation

The protein (1mg/ml) was lyophilized with no additives.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility

It is recommended to reconstitute the lyophilized Aprotinin in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source

Bovine Lung.

Stability

Lyophilized Aprotinin although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution Aprotinin should be stored at 4oC between 2-7 days and for future use below -18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Synonyms

Pancreatic trypsin inhibitor, Basic protease inhibitor, BPI, BPTI, Aprotinin, AP.
