MxBind™ Protein A/G Preclearing Beads #VB202

MxBind™ Protein A/G Preclearing Beads are mono-sized superparamagnetic beads covalently bound with recombinant A/G proteins. This recombinant protein contains 4 protein A and 2 protein G Fc-binding domains, making it an ideal tool for binding and purifying a wide range of immunoglobulins. Since human specimens such as nasopharyngeal swabs contain various classes of immunoglobins that can interfere with immunoassays, a preclearance step will help produce consistent results. We used MxBind™ Protein A/G Preclearing Beads in ELISA to preclear human nasopharyngeal swab specimens and found it not only necessary, but it also greatly reduced variations in results. In addition to its preclearance function, MxBind™ Protein A/G magnetic beads may also be used for immunoprecipitation and antibody purification.
