Description: Protein A/G Magnetic Beads for immunoprecipitation (IP) are based on a biological nanosurface technology (S-TEC). Protein A/G coats the surface of super paramagnetic microspheres with high coating density up to 9.3 × 10^13 molecules/cm2. Compared to similar immune magnetic beads, our Protein A/G beads display much more antibody binding sites therefore using less magnetic beads per reaction and ultimately achiving greater cost-efficiency. Non-specific binding is reduced to an absolute low eliminating any detectable interference with your IP assays. The large, specific surface area of the beads greatly shortens the adsorption time and achieves complete antibody/antigen adsorption process in 10 minutes and complete total purification and precipitation in just 30 minutes. This product can be used on a wide variety of samples, such as in cell lysates, supernatants collected from cell secretion, serum, ascites, and other immune antigens.
