特徴

• Protein 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 unlike Protein A 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.
• Applications:Suitable for use in ELISA and Western Blot.
• Other applications not tested.
