General description
Chemical structure: peptide
Biochem/physiol Actions
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.
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.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.
Other Notes
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)
