Jacalin is isolated from Jackfruit seeds and purified by affinity chromatography. It is a glycoprotein with two non-covalently bound subunits (14.6 and 17.1 kDa) 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. BioVision's 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 14 kDa and 17 kDa. Gene Bank Accession Number Q38720. MW: 14.6 kDa (β chain) and 17.1 kDa (full protein). Purity ≥ 97%
