Purity: > 90% by SDS - PAGE. Format: Liquid. In phosphate buffered saline (pH7.4), 10% glycerol.. Ahsg, also known as Alpha-2-HS-glycoprotein isoform 1, is probably involved in differentiation. Recombinant mouse ahsg, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
