| Product Name | Recombinant Human CEA Carcinoembryonic Antigen Protein >95% Purity Mammalian Expressed 1 mg |
| Catalog No. | AATM-HMM-0046 |
| Description | This recombinant human carcinoembryonic antigen (CEA) is expressed in mammalian cells and supplied as a liquid formulation. CEA is a glycoprotein widely used as a tumor marker, particularly for colorectal cancer monitoring, and serves as an essential component in diagnostic immunoassays. The protein exhibits an apparent molecular weight of 100-180 kDa as determined by SDS-PAGE, with a purity exceeding 95%. It is supplied at a concentration of 1-2 mg/ml formulated in 1×PBS at pH 7.4, packaged in 1 mg aliquots. This product is suitable for use as a calibrator or standard in diagnostic kits and for antibody preparation. |
| Intended Use | For research use only as a diagnostic calibrator or standard, and for antibody preparation in tumor marker assays. Not for use in human experiments. |
| Principle / Technology | Recombinant protein expression in mammalian cells with glycosylation patterns similar to native CEA, supporting accurate immunoassay performance. |
| Sample Type | Purified protein solution |
| Storage Conditions | Store at 4°C for short-term use or at -20°C for long-term storage. Avoid repeated freeze-thaw cycles. |
| Shelf Life | Stable for at least 12 months when stored at -20°C. |
