Beschreibung

General description

A reversible protease inhibitor produced by actinomycetes. Inhibits cathepsin A and B as well as papain, and trypsin-like serine proteases. Acts by forming a hemiacetal adduct between the aldehyde group of the inhibitor and the active proteinase. Effective at concentrations range from 1 to 100 µM.

Effective concentration: 1-100 µM.

Peptidyl arginine aldehyde protease inhibitor produced by actinomycetes. Inhibitor of Ca²⁺-dependent endopeptidases. Has specificity similar to Leupeptin (Cat. No. 108975). Inhibits trypsin-like serine proteases, papain and some cysteine proteases (IC₅₀ = 300 µM).

Biochem/physiol Actions

Cell permeable: no

Primary Target
trypsin-like serine proteases, papain, and some cysteine proteases

Product does not compete with ATP.

Reversible: yes

Target IC₅₀: 300 µM against trypsin-like serine proteases, papain and some cysteine proteases; Effective concentration: 1-100 µM

Preparation Note

Following reconstitution, aliquot and freeze (-20°C) for long term storage or refrigerate (4°C) for short-term storage. Stock solutions are stable for up to 1 week at 4°C or for up to 1 month at -20°C.
