Traditional immunoprecipitation using protein A or protein G agarose beads has long been a popular research method. Recently, scientists have replaced the agarose beads with magnetic beads for easier retrieval of the immunoprecipitated sample.
Millipore’s new PureProteome magnetic beads offer easy sample retrieval and the added benefit of faster immunoprecipitation. Side-by-side comparisons of agarose and magnetic beads in an immunoprecipitation assay demonstrated that the use of PureProteome beads yielded equivalent results while reducing incubation time from two hours to ten minutes. |
