Overview
AffiBEADS® Protein A/G Magnetic Beads use "nano-surface biotechnology" (S-TEC) to target Protein A/G onto the surface of superparamagnetic polymer microspheres with high density. It has higher antibody binding ability and very low non-specific adsorption rate of protein. One-step purification can isolate the antibody with purity >90% from the serum sample, which is simple and effective to use. Natural Protein A is a cell wall surface protein found in Staphylococcus aureus. Natural Protein G is a cell surface protein isolated from the genus G or C Streptococcus. Both have similar functions and bind most mammalian IgG by interacting primarily with the Fc region of immunoglobulin (Ig) , but differ in their binding specificity. Protein A/G MagBeads covalently conjugate both protein A and protein G, providing A wider binding range and higher utility than either protein A or protein G alone. At the same time, this product uses genetically modified proteins A and G, which not only maintain their Ig affinity properties, but also remove the non-major binding domain of the natural protein itself to reduce non-specific binding. This product has a wide range of application, can be used in cell lysis fluid, cell secretory fluid supernatant, serum, animal ascites and other immune antigen samples.
