Purity: > 95% by SDS - PAGE Format: Liquid. In 20 mM Tris-HCl buffer (pH8.0) containing 10% glycerol. AHSP(Alpha-hemoglobin stabilizing protein), also known as ERAF(Erythroid associated factor), is an erythroid-specific protein that acts as a chaperone to prevent the aggregation of alpha-hemoglobin during normal erythroid cell development. It specifically protects free alpha-hemoglobin from precipitation in live cells and in solution. This protein is downregulated in transmissible spongiform encephalopathies (TSEs). It is predicted to modulate pathological states of alpha-hemoglobin excess such as beta-thalassemia. Recombinant AHSP protein was expressed in E.coli and purified by using conventional chromatography techniques.
