• Cat.No.: Protein A-253S
• Product Overview: Recombinant Staphylococcus protein A was expressed in E.coli.

Specification

• Description: Protein A is a cell wall component produced by several strains of Staphylococcus aureus that consists of a single polypeptide chain and contains little or no carbohydrate. Recombinant Protein A is produced in E. coli and functions essentially the same as native Protein A. It consists of 5 IgG-binding domains E-D-A-B-C aligned in series.
• Source: E.coli
• Species: Staphylococcus
• Form: 20 mM sodium phosphate, pH 7.0 or 50 mM Tris-HCl buffer, pH 7.0.
• Molecular Mass: Recombinant Staphylococcus Protein A (rSPA) expressed in E. coli, which contains all five immunoglobin binding domains (E,D,A,B,C) and has a molecular weight of 46.6 kDa.
• Storage: Medium should be stored in neutral pH at 2 centigrade to 8 centigrade in the presence of a bacteriostat, e.g. 20% ethanol. Medium must NOT be frozen.
