SUMMARY Human antiactin antibodies were isolated from human smooth muscle antibodies by affinity chromatography using actin extracted from rabbit striated muscle and coupled to activated CH-Sepharose 4B. The eluate contained IgG and IgM smooth muscle antibodies reacting against muscularis mucosae of the stomach and blood vessels. Further the eluate contained IgM antibodies acting against the surface of isolated hepatocytes and the periphery of hepatocytes of sections of liver cells. These results indicate that antiactin antibodies possibly react with the hepatocyte membrane as has been described with regard to other antibodies.
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.
