Jacalin is an alpha-D-galactose binding lectin extracted from jack-fruit seeds (Artocarpus integrifolia). This lectin is a glycoprotein (approx. 40 kDa) composed of four identical subunits. Jacalin binds to human IgA1 (also called serum or secretory IgA) with high specificity (i.e., it does not bind IgG or IgM). Thus, Jacalin that has been immobilised on crosslinked beaded agarose is useful for purifying human IgA from serum or colostrum samples.

Streptavidin agarose consists of cross-linked agarose covalently coupled with pure streptavidin under controlled conditions. The stable linkage to the resin minimizes leaching of the streptavidin while maintaining full binding activity. The matrix is suitable for use in column and batch formats for any application that requires high biotin binding capacity and low non-specific binding. The resin has no detectable protease, DNase, or RNase contamination.
