Description générale
Protein G was initially isolated from G148, a human group G Streptococcal strain. It is a cell wall protein and shows high affinity to IgG (immunoglobulin G). It has a putative molecular weight of 30,000Da. It interacts with all subclasses of human IgG and also binds to mouse, rabbit and goat IgG.
Spécificité
Protein G is a cell wall protein, isolated from a specific bacterial strain, which has specific binding sites for certain classes of immunoglobulins from different species. Protein G binds nearly all subclasses of IgG, but no other classes of immunoglobulins.
Binding capacity: 20mg human IgG (polyclonal)/ml (the IgG is loaded at pH 7.0, and eluted with 200mM glycine, pH 2.8)
Structure: recombinant Protein G (E. coli, Mr = 22,000) is covalently coupled to crosslinked 4% agarose beads: 2.5mg Protein G (>98% pure)/1ml gel.

Application
Affinity chromatography using Protein G Agarose, like Protein A Agarose, is the method of choice for purification of IgG from many species. It has been used as a pre-clearing agent during-
- Ubiquitination assay
- Immunoprecipitation

Aberrant protocadherins (PCDHs) expression trigger tumor invasion and metastasis. PCDH20 anti-tumor functions in various tumor have been identified.
