  • RelevanceProtein G is a bacterial protein derived from the cell wall of certain strains of b-hemolytic Streptococcci. It binds with high affinity to the Fc portion of various classes and subclasses of immunoglobulins from a variety of species. Protein G binds to all IgG subclasses from human, mouse and rat species. It also binds to total IgG from guinea pig, rabbit, goat, cow, sheep, and horse. Protein G binds preferentially to the Fc portion of IgG, but can also bind to the Fab region, making it useful for purification of F(ab') fragments of IgG. Due to it's affinity for the Fc region of many mammalian immunoglobulins, protein G is considered a universal reagent in biochemistry and immunology.

Both protein A-HRP (e.g. ab7456) or protein G-HRP (e.g. ab7460) can be used to not detect the heavy and light chain of endogenous IgG in WB.

Application Other

Review text: Used for detection of primary antibody in WB after IP with the same antibody. In this case, IP was with goat anti HP1-alpha on Protein G beads, and detection was with goat anti HP1-alpha, and Protein G HRP. Detection was very specific, and eliminated heavy and light chains of denatured antibodies.
Sample: Human Cell lysate - nuclear
