Jacalin is a lectin composed of four subunits, two of approximately 10,000D and two of 16,000D each. This 50,000D glycoprotein appears to bind only O-glycosidically linked oligosaccharides, preferring the structure galactosyl (b-1,3) N-acetylgalactosamine. This structure (the so-called "T-antigen") is the oligosaccharide to which peanut agglutinin binds. However, unlike PNA, Jacalin will bind this structure even in a mono- or disialylated form. This lectin has been used to purify human IgA, since no other human immunoglobulin class binds Jacalin (references available upon request). The specificity of this lectin also affords the opportunity to localize or isolate glycoproteins with O-glycosidically linked oligosaccharide side chains.

Small volumes of Artocarpus integrifolia lectin vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS656114 is a lectin targeting Artocarpus integrifolia. Also known as Artocarpus integrifolia (Jacalin, Jackfruit).
