일반 설명
Genetically engineered truncated protein G; retains affinity for IgG, but lacks albumin- and Fab- binding sites and membrane-binding regions.
Protein G is a group G Streptococcus protein and is a large multi-domain cell wall protein. It interacts with the Fc region of IgG (immunolglobulin) through its repeating 55-amino acid domain. Strain GX7809 and GX7805 contain two and three such protein repeats respectively.
애플리케이션
Protein G has been used for the analysis of mAb (monoclonal antibody) synergy towards hCG (human chorionic gonadotropin) using surface plasmon resonance (SPR), and for serum IgG galactosylation obtained from RA (rheumatoid arthrtitis) patients and MRL-lpr mice.
생화학적/생리학적 작용
Protein G is implicated in the evasion of host defence response by Streptococcus, via its protein binding properties. It is interacts with α2-micorglobulin which is a predominant inhibitor of human plasma.
물리적 형태
Lyophilized from water.
