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.

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.
