This lectin consists of two 60 kDa subunits that can be dissociated by a reducing agent 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. The B chain binds to galactose or n-acetylgalactosamine residues of the membrane glycoconjugate. Luciferin labeled castor lectin I has the appropriate amount of fluorescent dye binding to provide the best staining properties for this lectin. This conjugated substance basically does not contain unconjugated fluorescent dyes. The excitation maximum is 495nm and the emission maximum is 515nm.
