Ricinus Communis lectin I (RCA I, RCA120), Unconjugated(catalog number :L-1080-10) consists of two 60 kDa subunits that can be dissociated by reducing reagents into a closely related chain between 27 kDa and 33 kDa. One of these chains appears to be common to the B chain of ricin, another castor agglutinin, while the other chain is specific to RCA I.
