Jacalin is an alpha-D-galactose binding lectin extracted from jack-fruit seeds (Artocarpus integrifolia). This lectin is a glycoprotein (approx. 40kDa) composed of four identical subunits. Jacalin binds to human IgA1 (also called serum or secretory IgA) with high specificity (i.e., it does not bind IgG or IgM). Thus, Jacalin that has been immobilized on crosslinked beaded agarose is useful for purifying human IgA from serum or colostrum samples.

Binding of IgA toimmobilized jacalin occurs at physiologic pH and ionic strength, as inphosphate-buffered saline (PBS). Elution of bound IgA occurs withcompetitor ligand (e.g., 0.1M melibiose or 0.1 M alpha-D-galactose) inPBS. IgD is reported to bind to jacalin (Aucouturier, et al., 1987).
