Studies of serum glycoproteins by paper electrophoresis in rheumatic fever showed the following: Total glycoproteins were generally increased in concentration, the alpha-2 glycoprotein fraction showed moderate to marked increases in value, and alpha-1 and beta glycoprotein components generally showed moderately decreased concentrations.
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.
