Biotinylated Human CEACAM-6/CD66c Protein, His-Avi Tag

Description :
FAQ COA 已发表文献 Carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM-6), previously called nonspecific crossreacting antigen (NCA) or CD66c, is one of seven human CEACAM family members within the immunoglobulin superfamily. Human CEACAM-6 is a 90 kDa, GPI-linked membrane protein that contains a 34 aa signal sequence, a 286 aa extracellular domain (ECD), and a 24 aa hydrophobic C-terminal propeptide. Mature human CEACAM-6 shows 84%, 85%, 80%, 87% and 51% aa identity to the equivalent extracellular regions of human CEACAMs 1, 5 (CEA) and 8, rhesus CEACAM-2, and bovine CEACAM-6, respectively. CEACAM-6 is expressed by granulocytes and their precursors. Activation enhances surface expression by mobilizing CEACAM-6 from storage in azurophilic granules. It often shows aberrant expression in acute lymphocytic leukemias. CEACAM-6 is also expressed in epithelia of various organs and is upregulated in pancreatic and colon adenocarcinomas and hyperplastic polyps. 产品性质 Synonyms CEACAM6; CD66c; CEAL; NCA; CEA Uniprot No. P40199 Source Recombinant Biotinylated Human CEACAM-6/CD66c Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Lys35-Gly320. Molecular Weight The protein has a predicted MW of 34.1 kDa. Due to glycosylation, the protein migrates to 55-75 kDa based on Tris-Bis PAGE result. Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Purity > 95% as determined by SDS-PAGE and HPLC Endotoxin 1.0EU per 1g of the protein by the LAL method. Formulation Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100g/mLis recommended. Dissolve the lyophilized protein in distilled water.
