– TargetMol Protein A Immunomagnetic Beads enables Protein A to cover superparamagnetic microspheres with high density by utilizing bio-nano technology. Protein AImmunomagnetic Beads can be used for the immunoprecipitation (IP) of proteins, protein complexes, protein-nucleic acid complexes, and other antigens. The Protein A Immunoprecipitation Kit comes with prepared buffers to provide a relatively better condition for immunoprecipitation and to enhance the stability. This product is suitable for antigen samples derived from cell lysates, cell culture supernatants, serum, ascites, and other sources.
