Product Details

Alternate Name CEACAM6, CD66c, CEAL, NCA
Gene Symbol CEACAM6
Gene ID 4680
Accession # P40199
Source HEK 293 cells
Appearance Lyophilized
Physical Form Description Lyophilized from 0.22 μm filtered solution in PBS, pH 7.4. Normally Mannitol or Trehalose are added as protectants before lyophilization.
Molecular Weight This protein rhCEACAM6 is fused with 6×his tag at C-terminus, has a calculated MW of 32 kDa expressed. The predicted N-terminus is Lys35. Protein migrates as 35-65 kDa in reduced SDS-PAGE resulting from glycosylation.
Purity by SDS-PAGE ≥95%
Endotoxin Level < 1.0 EU per μg of the rhCEACAM6 by the LAL method.
Biological Activity Measured by the ability of the immobilized protein to support the adhesion of calcium ionophore treated human neutrophils. When 2 x 105 cells/well are added to CEACAM6 coated plates (10 μg/mL, 100 μL/well), 45-70% of the cells will adhere after 20 minutes
Reconstitution Instructions Centrifuge the vial prior to opening. Reconstitute in PBS, pH 7.4. Do not vortex.
Handling Centrifuge the vial prior to opening.
Storage Conditions -20°C
Shipping Conditions Gel Pack
USAGE For Research Use Only! Not to be used in humans


Carcinoembryonic antigen-related cell adhesion molecule 6 (non-specific cross reacting antigen) (CEACAM6) also known as CD66c (Cluster of Differentiation 66c), CEAL, NCA, and is one of seven human CEACAM family members within the immunoglobulin superfamily. In humans, CEACAMs include type I transmembrane proteins (CEACAM1, CEACAM3, and CEACAM4) and GPI-linked molecules (CEACAM5 through CEACAM8). There is no human CEACAM2. CEACAM 6 contains one N-terminal V-type Ig-like domain (N domain), followed by two C2-type Ig-like domains. It shows considerable glycosylation, including (sialyl) LewisX, which mediates binding to E-selectin, galectins and some bacterial fimbrae. CEACAM-6 is expressed by granulocytes and their progenitors. It is also expressed by epithelia of various organs and is upregulated in pancreatic and colon adenocarcinomas, as well as hyperplastic polyps. Resistance to adhesion-related apoptosis in tumor cells is conferred in the condition of CEACAM6 overexpression.
