IgG F(c)-Receptor
基本信息
| MDL number | MFCD00132110 |
| NACRES | NA.26 |
| General description【一般描述】 | Protein G, a cell wall protein, is obtained from group G streptococci. The extracellular part of this protein is made of two/three small domains or serum albumin binding (GA domains) and two/three immunoglobulin (IgG) binding domains (B domains). Genetically engineered truncated protein G; retains affinity for IgG, but lacks albumin and Fab binding sites and membrane-binding regions. |
| Application【应用】 | Protein G′ from Streptococcus sp. has been used in in vitro actin labeling assay. |
| Biochem/physiol Actions【生化/生理作用】 | Protein G can bind all the human and mouse IgG subclasses. It can bind to both the fragment crystallizable (Fc) and antigen-binding fragment (Fab) components of the antibody. |
| Physical form【外形】 | lyophilized powder in a Tris-HCl buffer, pH 7.5 |
