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.
Physical form
Suspension in 20% ethanol
Preparation Note
Prepared with recombinant streptococcal Protein G from which the albumin-binding region has been genetically deleted

Recently, the nuclear protein known as Poly (ADP-ribose) Polymerase1 (PARP1) was shown to play a key role in regulating transcription of a number of genes and controlling the nuclear sub-organelle nucleolus. PARP1 enzyme is known to catalyze the transfer of

Properdin is a positive regulator of complement activation so far known to be instrumental in the survival of infections with certain serotypes of Neisseria meningitidis. We have generated a fully backcrossed properdin-deficient mouse line by conventional gene-specific targeting. In vitro

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
