Ricinus Communis Agglutinin I (RCA I, RCA120), Unconjugated (Catalog Number: L-1080-10) consists of two subunits of 60 kDa which can be dissociated by reducing agents into closely related chains between 27 kDa and 33 kDa. One of the chains appears to be common to the B chain of another castor bean lectin, ricin, while the other chain is unique to RCA I.
