Purity: > 90% by SDS - PAGE Format: Liquid. In 20mM Tris-HCl buffer (pH8.5) containing 40% glycerol, 0.2M NaCl, 0.1mM PMSF. Crmp1, also known as Collapsin response mediator protein 1, is necessary for signaling by class 3 semaphorins and subsequent remodeling of the cytoskeleton. It plays a role in axon guidance, invasive growth and cell migration and may participate in cytokinesis. Recombinant mouse Crmp1, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
