This lectin only binds O-glucosid-linked oligosaccharides, preferring the structure of galactosyl (beta-1,3) n-acetylgalactosamine. This structure (T antigen) is a peanut lectin (PNA) -bound oligosaccharide. However, unlike PNA, Jacalin will bind the monoaqueous or diaqueous forms of acidification of this structure. This lectin has been used to purify human IgA. The specificity of this lectin also provides an opportunity to locate or isolate glycoproteins with oligosaccharide side chains with O-glucoside connections. Biotinylated Jacalin has the right amount of biotin binding to provide the best staining properties for this lectin. This conjugate contains essentially no unconjugated biotin and is preserved with sodium azide.
