Lectinochemical studies on the binding properties of a toxic lectin (ricin) isolated from the seeds of Ricinus communis.

Abstract

BACKGROUND Ricin (RCA2 or RCA60) is a highly toxic heterodimeric protein found in the seeds of the castor plant Ricinus communis. It is a potential biohazard. In the present study, the fine specificity of ricin was defined. METHODS The combining site of ricin was characterized by quantitative precipitin (QPA) and precipitin inhibition assays (QPIA… (More)
