Protein purification reagents are for use in isolating one or more proteins from a complex mixture, usually cells, tissues, or whole organisms. This process is vital for function and structure characterization, as well as identifying interactions of the protein of interest. Important during the many steps, the protein purification reagents assist with cell lysis, separating the soluble protein components from cell debris, and finally separating the protein of interest from product- and process-related impurities.

Concanavalin A agarose
Supplier: G-Biosciences
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.
