Clasto-lactacystin β-lactone
Product Source:
Synthetic
Potent, highly specific, irreversible and cell-permeable inhibitor that covalently modifies the catalytic β subunits of the proteasome. The β-lactone intermediate is generated from the aqueous hydrolysis of lactacystin, and is the active inhibitory species that reacts with the proteasome.
