The regulatory elements of araBAD operon, contrary to lac‐based expression systems, afford hypersynthesis of murine, and human interferons in Escherichia coli
Abstract:The overexpression of four different interferons, i.e., murine interferon alpha1 and human interferons alpha1, alpha 8, and alpha 21 was challenged in Escherichia coli. Synthetic genes coding for these interferons were designed, assembled, and cloned into the vector pET9a (using the NdeI and BamHI sites), placing interferon expression under the control of phage T7 promoter. Despite an intensive screening for optimal culture conditions, no interferon synthesis was observed using overexpression systems based on … 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.
