Protein A, Recombinant (ProA, Staphylococcus A Protein)
Description
Purity ~95% (SDS-PAGE). 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. Protein A is suitable for use as an antigen, as a control or standard in assays, for conjugation and for most other immunological methods. This recombinant Protein A contains only IgG binding domains, ensuring maximum specific IgG binding. Applications: Suitable for use in ELISA and Western Blot.
