Protein A (ProA, Staphylococcus A Protein) (Biotin)
Description
Purified by Protein A affinity chromatography. Protein A is a surface protein (approximately 56kD in size) originally discovered within the cell wall of Staphylococcus aureus. While important for bacterial survival, Protein A has beneficial uses in immunology for its high affinity binding to immunoglobulins (especially the IgG isotype). This high affinity property makes Protein A essential in the large scale purification. Source: This product was prepared from chromatographically pure Protein A. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-biotin and anti-Protein A. Applications: Suitable for use in ELISA, Western Blot and Immunohistochemistry.
