Active Recombinant Human CEACAM1 protein(Met1-Gly428), His-tagged

• Cat.No.: CEACAM1-5078H
• Product Overview: Recombinant Human CEACAM1 (NP_001020083.1) (Met 1-Gly 428) was expressed in HEK293 with a C-terminal polyhistidine tag.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: Met1-Gly428
• Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: 1. Measured by its ability to bind biotinylated Human CEACAM6-His in functional ELISA. 2. Measured by its ability to bind biotinylated Human CEACAM8-His in functional ELISA.3. Measured by its ability to inhibit IL­2 secretion by HuT 78 human cutaneous T cell lymphoma cells. The ED50 for this effect is typically 2­13 μg/mL.
• Molecular Mass: The secreted recombinant human CEACAM1 comprises 405 amino acids and predicts a molecular mass of 44.8 kDa. As a result of glycosylation, the apparent molecular mass of rhCEACAM1 is approximately 60.5 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 95 % as determined by SDS-PAGE
• 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°C before opening to recover the entire contents.
