概述

Concanavalin A (Con A) Agarose consists of Con A coupled to 4% agarose by the cyanogen bromide method. Con A is a tetrameric metalloprotein lectin isolated from Canavalia ensiformis (jack bean). Con A 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. Con A agarose 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, Con A is a metalloprotein and to maintain its binding characteristics the presence of both Mn2+ and Ca2+ is essential. Each subunit of Con A utilizes one calcium and one manganese ion and these cations can be removed under acidic conditions abolishing the carbohydrate-binding activity.

应用

For purification/ enrichment of glycoproteins, polysaccharides and glycolipids.
