Product Description
Specifications
| Size | 10 µg, 50 µg, 100 µg |
| Estimated Lead Time | 2-3 business days |
| Species | Human |
| Accession Number | Q8N4D0 |
| Gene Symbols | CEACAM5 |
| Protein Name / Synonyms | Carcinoembryonic Antigen-Related Cell Adhesion Molecule 5, CEA, Meconium Antigen 100, CD66e, Carcinoembryonic Antigen, CD66e Antigen |
| Expressed Region | Lys35-Ala685 |
| Expression System | HEK293 cells |
| Conjugation | Biotin |
| Tag | N-terminal 8x histidine tag. The primary amino groups (-NH2) at the N-terminus and the side chains of lysine (K) residues were biotin-conjugated using the standard chemical labeling method. |
| 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. |
| Format | Lyophilized powder |
| Formulation | Lyophilized from a 0.2 µm filtered solution in PBS |
| Concentration (lot specific) | Determined by BCA protein assay kit (Thermo Scientific) |
| Preservative | None |
| Reconstitution | Briefly spin the vial and bring the contents to the bottom prior to opening. It is recommended to reconstitute at 0.5 - 1.0 mg/mL with sterile deionized water or 1x PBS. |
| Endotoxin Level | Not determined |
| Protein Type | Recombinant Protein |
| Shipping Type | Ambient temperature |
| Storage | -20°C |

Stability & Storage
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.
