Abstract:Binding sites of peanut agglutinin (PNA), Ulex euwpaeus (UEA-1), concanavalin A (Con A), and wheat germ agglutinin (WGA) were localized in 10 granulosa cell tumors, 10 Sertoli-Leydig cell tumors, 4 theca cell tumors, and 5 small cell carcinomas. Con A and WGA reacted positively with the majority of the studied neoplasms. PNA and UEA-1 were persistently negative in the sex cord-stromal tumors (SCST) but showed focal positivity in small cell carcinomas. Negative reactions of SCST with PNA and UEA-1 may serve for… Show more
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.
