MxBindTM protein A/G magnetic beads are mono-sized superparamagnetic beads with superior quality, delivering consistency, reproducibility, and low background binding. Compared to conventional method for isolation of proteins (e.g. IgG) by centrifugation and filtration, MxBindTM protein A magnetic beads are extremely convenient to use. All you need is a magnetic stand to magnetically separate the target molecules from a complex protein mixture; it is fast, flexible, and efficient. MxBindTM protein A/G magnetic beads are an ideal tool to preclear human nasopharyngeal swab specimens used for ELISA application.
