Despite these limitations, however, and in view of the high purity of the C14-dextran used,2 the data clearly establish that the precipitin produced by human beings in response to the injection of small amounts of dextran is indeed antibody to dextran.
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.
