Source

Gene Symbols:
  • CEACAM5
Species:
Human
Accession Number:
  • Q8N4D0
Expressed Region:
Lys35-Ala685
Protein Name & Synonyms:
Carcinoembryonic Antigen-Related Cell Adhesion Molecule 5, CEA, Meconium Antigen 100, CD66e, Carcinoembryonic Antigen, CD66e Antigen

Preparation

Expression System:
Human Embryonic Kidney 293 Cells
Conjugation/Tag:
N-terminal 6x histidine tag
Purification:
His-tag affinity purification by immobilized metal ion affinity chromatography (IMAC)
Purity:
> 95%
Purity determined by:
SDS-PAGE under reducing conditions and visualized by Coomassie blue staining
Molecular Weight (kDa):
The recombinant human CEA has a calculated molecular mass of 71 kDa. Due to the abundant glycosylation, it migrates as approximately 125-150 kDa protein bands (confirmed by Western blotting) in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions.

Storage/Stability
Upon arrival, the lyophilized protein may be stored for 2 weeks at 4°C. For long term storage, it is recommended to store desiccated below -20 °C in a manual defrost freezer. Following reconstitution, the protein may be stored for 2 weeks under sterile conditions at -20 °C.  For long term storage, it is recommended to make appropriate aliquots and store at -80 °C. Avoid repeated freeze-thaw cycles.
