Abstract:A simple one-step method for the purification of recombinant His-tagged profilin from the bacterial cell lysate is reported. Noting the greater ease with which hexahistidine-tagged proteins can be metalprecipitated compared with unwanted protein impurities, we investigated the effect of lysis-buffer additives and optimization of other conditions to recover selectively desired proteins in a one-step metal precipitation without using biopolymers. Purification of the His-tagged melon (Cucumis melo) profilin was u… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
