Application:	Antipain dihydrochloride from microbial source has been used in the preparation of adipocyte proteins for western blotting and in protease inhibitor cocktail for isolating nuclear extracts for gelshift analysis.
Application:	Concentrations for 50% inhibition (μg/ml): papain, 0.16 trypsin, 0.26 cathepsin A, 1.19 cathepsin B, 0.59 cathepsin D, 125 plasmin, >93 chymotrypsin and pepsin, >250 It also has been reported to inhibit calpain I, (porcine) with K_i = 1.4 μM
Biochem/physiol Actions:	Antipain dihydrochloride also inhibits the action of papain and cathespsin B.
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 of antipain can reduce the frequency of chemically induced transformation in BALB/c-/3T3 cells.
General description:	Chemical structure: peptide
Packaging:	1, 5, 25, 100 mg in glass bottle
Preparation Note:	Solubility testing at 50 mg/ml in water yields a clear to slightly hazy yellow solution. It is reportedly soluble in methanol, water, and DMSO; less soluble in ethanol, butanol, and propanol; insoluble in benzene, hexane, and chloroform.⁸ A stock solution in water or buffer is stable for about a month at -20 °C. Dilute solutions should be stored on ice and kept for only a day because of the terminal aldehyde, which is subject to oxidation and racemization.
Preparation Note:	Stock solutions in water or buffer stable for 1 week at 4 °C, 1 month at −20 °C.
