SOME IMMUNOCHEMICAL PROPERTIES OF PENICILLENIC ACID

Abstract
Under mild conditions, benzylpenicillin in aqueous solution rearranges to benzylpenicillenic acid, which reacts, under suitable conditions, to form stable disulfides and mercaptides. Through reaction with native proteins or especially with proteins that are enriched in SH groups ("thiolated"), penicillenic acid forms, ma mixed disulfide linkages, stable highly substituted conjugates.
