Protein A, Biotinylated

Protein A, Biotinylated

Biotinylated Recombinant Protein A that has been covalently conjugated to biotin molecules.

 

Protein A is a cell wall component produced by a number of strains of Staphylococcus aureus. It consists of a single polypeptide chain with few or no carbohydrate. Recombinant Protein A is produced in E. coli and in the same manner as native Protein A. The Protein A molecule contains four high-affinity binding sites that can interact with the Fc region from IgG of a number of species. Optimal binding occurs at pH 8.2, but binding is also effective at physiological conditions (pH 7.0 to 7.6).
