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.
