Description : CEACAM5, also known as CEA or D66e, belongs to the large CEACAM subfamily of immunoglobulin superfamily. CEACAM5 is expressed primarily by epithelial cells, and is synthesized as a glycoprotein with a MW of 18 kDa comprising 6% carbohydrate. CEACAM5 contains one Ig-like V-type domain at the N-terminus, followed by six Ig-like C2-type domain and a GPI anchor, and exists as a homodimer. CEACAM5 and CEACAM6 are overexpressed in many cancers and are associated with adhesion and invasion. CEACAM5 can mediate cell-cell adhesion through homotypic and heterotypic interactions. It functions as a homotypic intercellular adhesion molecule and serves as a widely used tumor marker, since it is expressed at higher levels in tumorous tissues than in corresponding normal tissues. CEACAM5 has also been shown to contribute to tumorigenicity by inhibiting cellular differentiation. In addition, CEACAM5 is identified as the host receptor for the Dr family of adhesins of E.Coli, and the binding of E.coli Dr adhesins leads to dissociation of the CEACAM5 homodimer.
Source : HEK293
Species : Human
Tag : His
Predicted N Terminal : Lys 35
Form : Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Molecular Mass : The secreted recombinant human CEACAM5 consists of 662 amino acids and has a predicted molecular mass of 72.8 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhCEACAM5 is approximately 100-110 kDa due to glycosylation.
Protein length : Met1-Ala685
Endotoxin : < 1.0 EU per μg protein as determined by the LAL method.
Purity : > 95 % as determined by SDS-PAGE.
Stability : Samples are stable for up to twelve months from date of receipt at -70 centigrade.
Storage : Store it under sterile conditions at -20 centigrade to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4℃ before opening to recover the entire contents.
Shipping : In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

Ask a question
Can CEACAM5 levels be used to detect cancer in its early stages? 03/28/2021

CEACAM5 can be a helpful marker, but it is not typically used for early cancer detection.

Are there any limitations to using CEACAM5 as a cancer marker? 04/07/2018

CEACAM5 is not specific to a single cancer type and may also be elevated in non-cancerous conditions.

What other medical conditions or diseases can cause an increase in CEACAM5 levels? 02/14/2018

Conditions like hepatitis, pancreatitis, and some non-cancerous gastrointestinal diseases can also elevate CEACAM5 levels.

How is CEACAM5 protein used in cancer treatment monitoring? 12/27/2016

CEACAM5 levels are monitored to assess the effectiveness of cancer treatment and to detect cancer recurrence.

Can CEACAM5 levels vary between different individuals, and if so, why? 12/03/2016

Yes, CEACAM5 levels can vary between individuals due to genetic factors and other individual-specific variables.
