Recombinant Cynomolgus CEACAM5 Protein (Met1-Ala688), His-tagged

• Cat.No.: CEACAM5-1025C
• Product Overview: Recombinant Cynomolgus CEACAM5 Protein (XP_005589491.1) (Met1-Ala688) was produced by HEK293 Cells expression system. This protein was expressed with a polyhistidine tag at the C-terminus.

Specification

• Source: HEK293
• Species: Cynomolgus
• Tag: His
• Form: Lyophilized from sterile 50 mM Tris, pH 8.0.
  Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The recombinant CEACAM5 consists of 665 amino acids and predicts a molecular mass of 73.5 kDa. As a result of glycosylation, it migrates as an approximately 105-140 kDa band in SDS-PAGE under reducing conditions.
• Protein Length: Met1-Ala688
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: ≥ 90 % as determined by SDS-PAGE. ≥ 95 % as determined by SEC-HPLC.
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. 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 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.

Q&As

Can CEACAM5 levels be used to detect cancer in its early stages?

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?

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?

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

How is CEACAM5 protein used in cancer treatment monitoring?

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?

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