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.

Thiophilic adsorption or thiophilic chromatography is a routinely used technique for the low cost, simple purification of immunoglobulins. Thiophilic adsorption was first developed by Porath et al in 1984 and is a group specific, salt-dependent purification technique that has distinct affinity towards immunoglobulins and α2- macroglobulins. The thiophilic adsorption works on the principle that some proteins in high salt are able to bind to an immobilised ligand that contains a sulfone group in proximity to a thioether group. The bound proteins are then eluted in decreasing salt concentrations. The thiophilic resin binds immunoglobulins, including IgG, IgY and IgM, from serum, ascites or tissue culture supernatants and the purified immunoglobulins are then eluted in a near neutral aqueous buffer.

Streptavidin Resin is designed for the single step small and large scale affinity purification of proteins and antibodies with a biotin tag. Biotin, a 244 Da vitamin (Vitamin H) molecule, exhibits an extraordinary binding affinity for avidin (Ka=10¹⁵ M⁻¹) and streptavidin (Ka=10¹⁵ M⁻¹). Biotin and (strept)avidin interaction is rapid and once the bond is established it can survive up to 3M guanidinehydrochloride and extremes of pH. Biotin-avidin bonds can only be reversed by denaturing the avidin protein molecule with 8M guanidine-hydrochloride at pH 1,5 or by autoclaving. The biotinylated molecules are efficiently probed with avidin or streptavidin conjugated to reporter molecules, such as peroxidases or phosphatases.

Protein A is a type I membrane protein produced by several strains of Staphylococcus aureus. It has high-affinity binding sites that enable the purification of IgG obtained from various species such as humans, rabbit, mouse, and bovine. Protein A Agarose is prepared using a covalent coupling method that maintains the stability and binding characteristics of the product.
By using our resin, human IgGs can be eluted under milder conditions (such as at pH 4.0) as compared to elution by conventional methods.
