Jacalin, Unconjugated

Product Details

Jacalin, Unconjugated, 25 mg. Jacalin appears to bind only O-glycosidically-linked oligosaccharides, preferring the structure galactosyl (beta-1,3) N-acetylgalactosamine. This structure (the T-antigen) is the oligosaccharide to which peanut agglutinin (PNA) binds. However, unlike PNA, Jacalin will bind a mono- or disialylated form of this structure. This lectin has been used to purify human IgA. The specificity of this lectin also affords the opportunity to localize or isolate glycoproteins with O-glycosidically-linked oligosaccharide side chains.
