Protein G is a surface protein of two groups of Streptococcal bacteria that has the ability to bind immunoglobulins. Similar to Protein A, but with slightly different specificity, Protein G is an important agent in the purification of proteins due to its ability to bind the Fc region. While native Protein G binds to albumin, recombinant Protein G is designed to contain only immunoglobulin binding domains to ensure the maximum specific IgG binding capacity. Protein G Biotin Conjugated is ideal for investigators involved in Signal Transduction, Molecular Biology, Cancer, and Cell Signaling.

Application Note

Protein G Biotin Conjugated is suitable as a detection agent for primary antibodies that are of the IgG isotype.


Protein G Biotin Conjugated was prepared from chromatographically pure recombinant Protein G.  Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-biotin and anti-Protein G. No reaction was observed against anti-Protein A.
