SuRi rProtein A Agarose Resin

Natural Protein A is a cell wall surface protein found in Staphylococcus aureus, it is similar to protein G isolated from the genus G or C Streptococcus, bind most mammalian IgG by interacting primarily with the Fc region of immunoglobulin (Ig), but differ in their binding specificity. It can be used for the separation and purification of a variety of antibodies (monoclonal antibody and polyclonal antibody). Protein A and Protein G differ in their binding properties to different immunoglobulin subclasses (see Appendix 1 for details). This product uses genetically modified protein A, which not only maintains its Ig affinity properties, but also remove the non-major binding domain of the natural protein itself to reduce non-specific binding. SuRi rProtein A Agarose Resin, which is highly cross-linked agarose gel as the matrix and modified alkali-resistant recombinant protein A as a ligand, has high physicochemical stability. High purity antibody can be obtained from ascites, serum and culture medium samples by one-step affinity chromatography with this product, which is convenient to use and widely used.
