Pierce™ Recombinant Protein G (from E. coli)
Proteins and Peptides
Pierce™ Recombinant peroxidase conjugated (HRP-Horseradish Peroxidase) protein G can be used to probe and detect rabbit and human antibodies, especially IgG isotypes, in western blotting, ELISA, IHC and other immunoassay protocols.

  • Contains two Fc-binding domains per protein
  • Does not bind human IgM, IgD or IgA
  • More efficient than protein A for mouse (IgG1), human (IgG3) and rat, goat and cow antibodies
  • Less efficient than protein A for guinea pig, pig, dog and cat

Protein G is a bacterial cell wall protein isolated from group G Streptococci. DNA sequencing of native protein G identifies two IgG-binding domains and sites for albumin and cell surface binding. The albumin and cell surface binding domains have been eliminated from recombinant protein G to reduce non specific binding and, therefore, can be used to separate IgG from crude samples. Optimal binding occurs at pH 5, although binding is also effective at pH 7,0 to 7,2.
