Jacalin is isolated from Jackfruit seeds and purified by affinity chromatography. It is a glycoprotein with two non-covalently bound subunits (14.6 and 17.1kD) and belongs to the family of galactose-binding lectins. Jacalin is preferably used in applications to isolate IgA from human serum, isolating human plasma glycoproteins and for applications in histochemistry. Jacalin is supplied as a white to light-yellow lyophilized powder without additives. The purity of the lectin is determined by SDS-PAGE, generating two homogeneous bands at 14kD and 17kD.
