Antipain dihydrochloride（Cat No.:I004267）is a reversible protease inhibitor that selectively targets serine and cysteine proteases, including trypsin, papain, and cathepsins. By blocking proteolytic activity, it prevents unwanted protein degradation, making it highly useful in biochemical, cell biology, and molecular biology research. Antipain dihydrochloride is commonly employed in protein isolation, enzyme assays, and studies of protease-regulated pathways. The dihydrochloride salt improves solubility and stability for laboratory use. Its broad inhibitory profile makes it a valuable tool for investigating protease function, apoptosis, and therapeutic enzyme-targeting strategies.
