Concanavalin A (Con A) agarose consists of Con A coupled to 6% agarose by the cyanogen bromide method. Con A is a tetrameric metalloprotein lectin isolated from Canavalia ensiformis (jack bean). It is used for the purification of glycoproteins, polysaccharides and glycolipids as it binds molecules containing α-D-mannopyranosyl, α-D-glucopyranosyl and sterically related residues. It has also be used in other application areas including purification of enzyme-antibody conjugates, purification of IgM and separation of membrane vesicles. As stated above, it is a metalloprotein and to maintain its binding characteristics the presence of both Mn²⁺ and Ca²⁺ is essential. Each subunit of Con A utilises one calcium and one manganese ion and these cations can be removed under acidic conditions abolishing the carbohydrate-binding activity.

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.
