Scientific Background: | Staphylococcus aureus Protein A is a 42 kDa cell wall constituent that is characterized by its binding affinity to the Fc portion of some immunoglobulins, especially the IgG class. The IgG binding domain (domain B) consists of three anti-parallel alpha-helices, the third of which is disrupted when the protein is complexed with Fc. Protein A is commonly used to purify antisera and in commonly used immunodetection and visualization techniques. Protein A participates in a number of protective biological functions including anti-tumor, toxic and carcinogenic activities, thus necessitating the removal of potential Protein A contaminants from antibody preparations for therapeutic use. | |
Technical Info/Product Notes: | Assay recognition of different Protein A constructs from natural Protein A from S. aureus (M), recombinant Protein A from E. coli (R), recombinant Cys-Protein A from E. coli (G), and recombinant alkaline-resistant Protein A variant from E. coli (S) were tested and the resulting concentrations were interpolated from kit standard curve and displayed in the figure provided.
