Purity: > 90% by SDS - PAGE Format: Liquid. In 20mM Tris-HCl buffer (pH 8.0) containing 0.15M NaCl, 10% glycerol. . CEACAM7 belongs to the immunoglobulin superfamily This protein contains 1 Ig-like C2-type (immunoglobulin-like) domain and 1 Ig-like V-type (immunoglobulin-like) domain. CEACAM7 is strongly down-regulated in colonic adenocarcinomas. Recombinant human CEACAM7 fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
