Back Cover: Aggregation‐prone antibody single‐chain variable fragments (scFv) are refolded from urea solutions in the presence of amphiphilic derivatives of poly(sodium acrylate) playing the role of artificial chaperons. Weak noncovalent interactions with the polymers impart solubility to partly‐folded scFv intermediates, resulting in recovery of the native‐like structure. This is reported by Nicolas Martin, Narciso Costa, Frank Wien, Françoise M. Winnik, Céline Ortega, Amaury Herbet, Didier Boquet, and Christophe Tribet, article number 1600213.
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.
