Active Recombinant Human CEACAM5 protein(Lys35-Ala685), His-tagged

Specification :
| Source : HEK293 | Species : Human | Tag : His | Form : Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. | Bio-activity : Immobilized Human CEACAM-5, His Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Anti-CEACAM5 Antibody, hFc Tag with the EC50 of 8.3ng/ml determined by ELISA. | Molecular Mass : The protein has a predicted MW of 72.42 kDa. Due to glycosylation, the protein migrates to 100-140 kDa based on Tris-Bis PAGE result. | Protein Length : Lys35-Ala685 | Endotoxin : Less than 1EU per μg by the LAL method. | Purity : > 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC | Storage : -20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles. | Reconstitution : Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
