  Used to detect immunoglobins in immunochemical assays

• 一般的な説明

  Protein A is a highly stable cell surface receptor produced by several strains of Staphylococcus aureus. This protein is capable of binding to the Fc portion of immunoglobulins, especially IgGs, from a large number of species. One protein A molecule has been shown to bind at least 2 molecules of IgG simultaneously. The IgG binding domain of Protein A consists of three anti-parallel alpha-helicies, the third of which is disrupted when the protein is complexed with the Fc region of the immunoglobulins. Protein A will bind the Fc portion of human IgG subclasses, IgM, IgA and IgE; and mouse IgG1 (weakly), IgG2a, and IgG2b. Protein A also associates with IgGs from other species, including monkey, rabbit, pig, guinea pig, dog, and cat.
  Protein A is involved in regulating anti-tumor, toxic, and carcinogenic functions. In addition to acting as an immunomodulator, it also has antifungal and antiparasitic properties.
