Is it possible to use Protein G for IP with rabbit antibodies or Protein A for IP with mouse antibodies?

While both Protein A and Protein G beads can be used successfully with rabbit and mouse antibodies, we recommend using Protein A beads when working with rabbit antibodies and Protein G beads when working with mouse antibodies. 这归因于蛋白 A 珠对兔 IgG 具有较高亲和力，而蛋白 G 珠对小鼠 IgG 具有较高亲和力。
