Beads-Protein G is designed as a rapid and simple tool or immunoprecipitation, purification/ depletion assays, and other magnetic separation applications. Antibody can easily bind to the Beads due to its’ high affinity with protein G. Via the antibody specific binding ability, the target protein along with Beads-Protein G could be temporarily immobilized at tube wall, so the other parts in the supernatant can be removed easily and efficiently under magnetic attraction.
