Description

General description

Chemical structure: peptide

Biochem/physiol Actions

Reversible inhibitor of serine/cysteine proteases and some trypsin-like serine proteases. Its action resembles leupeptin; however, its plasmin inhibition is less and its cathepsin A inhibition is more than that observed with leupeptin. Chronic administration can reduce the frequency of chemically induced transformation in BALB/c-/3T3 cells.

Inhibits serine/cysteine proteases and some trypsin-like proteases. Compare activity to that of leupeptin. Used to evaluate the role of proteases in cell transformations. Used to help identify new proteases.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Unit Definition

1 U corresponds to the amount of inhibitor which reduces the trypsin activity by 1 BAEE-U. (1 BAEE-U is the amount of enzyme which increases the absorbance at 253 nm by 0.001 per minute at pH 7.6 and 25°C; BAEE, Cat. No. 12880, as substrate)

Other Notes

Protease inhibitor
