Protein A, S. aureus, Cowan Strain Reagent – Agarose

Protein A isolated from Staphylococcus aureus, Cowan strain, is a 41,000D protein capable of binding to the Fc portion of immunoglobulin. This interaction is not species specific, as Protein A has been shown to bind IgG from a variety of species. The binding was thought to be restricted to IgG but subsequent studies have demonstrated that Protein A can interact with IgA, IgM, and subclasses of IgG from different species. Protein A is attached through a stable linkage to heat stable, cross-linked 4% agarose beads. The method of attachment allows for maximum immunoglobulin binding capacity and ease of elution. Agarose Protein A can be used for immunoglobulin purification, immunoprecipitation of antigens or other applications involving specific immunoglobulin binding. Protein A has been coupled at 2mg/ml of gel.

Small volumes of Protein A, S. aureus, Cowan Strain reagent vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
