General description

Protein G is an immunoglobulin (IgG)-binding bacterial cell wall protein isolated from group G streptococcal strain, G-148. This protein can be extracted from the cells by papain digestion and purified by the sequential use of ion-exchange chromatography on DEAE-Sephadex, affinity chromatography on Sepharose-coupled human IgG, and gel chromatography on Sephadex G-200. The binding between protein G and various polyclonal and monoclonal IgG is basically pH dependent between 2.8 and 10, with the strongest binding at pH 4 and 5, and weakest at pH 10. It acts as a powerful reagent for the detection of IgG.

Application

Protein G-Sepharose® is used in affinity chromatography, protein chromatography, antibody purification and characterization, immunoaffinity matrices, protein A, G and L resins, protein interaction, and purification and detection. Protein G-Sepharose® has been used to develop a strategy to confirm the presence of anti-erythropoietin neutralizing antibodies in human serum as well as to compare methods for depletion of albumin and IgG from equine serum.

Poly(ADP-ribose) polymerase 1 protein (PARP1) mediates chromatin loosening and activates the transcription of inducible genes, but the mechanism of PARP1 regulation in chromatin is poorly understood. We have found that PARP1 interaction with chromatin is dynamic and that PARP1 is...

Following infection with respiratory syncytial virus (RSV), reinfection in healthy individuals is common and presumably due to ineffective memory T cell responses. In peripheral blood of healthy adults, a higher CD4(+)/CD8(+) memory T cell ratio was observed compared with the...

Collective cell migration occurs in a range of contexts: cancer cells frequently invade in cohorts while retaining cell-cell junctions. Here we show that collective invasion by cancer cells depends on decreasing actomyosin contractility at sites of cell-cell contact. When actomyosin...
