| Product Name | Recombinant Human HE4 His Tag Protein >90% Purity HEK293 Expressed 1 mg |
| Catalog No. | AATM-HMM-0049 |
| Description | This recombinant human epididymis protein 4 (HE4) carries a His tag and is expressed in HEK293 mammalian cells. HE4 is a secreted glycoprotein that serves as a valuable serum biomarker for ovarian cancer, particularly in combination with CA125 for differential diagnosis. The protein has an apparent molecular weight of 23-27 kDa and is supplied at a concentration of 1-2 mg/ml with purity exceeding 90%. It is formulated in 1×PBS at pH 7.4 and provided in 1 mg aliquots. This product is suitable for antibody preparation, calibrator and quality control material formulation, and ovarian cancer diagnostic research. |
| Intended Use | For research use only in ovarian cancer diagnostic research, antibody preparation, and calibrator formulation. Not for use in human experiments. |
| Principle / Technology | Recombinant protein expression in HEK293 cells with His tag for affinity purification and functional analysis. |
| 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. |
