Recombinant Human DPP4 protein(Asn29-Pro766), C-His-tagged

Specification :
| Source : HEK293 | Species : Human | Tag : C-His | Protein length : Asn29-Pro766 | Form : Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. | Bio-activity : Immobilized Human DPPIV, His Tag at 1ug/ml (100ul/well) on the plate. Dose response curve for Anti-DPPIV Antibody, hFc Tag with the EC50 of 4.9ng/ml determined by ELISA. | Molecular Mass : The protein has a predicted MW of 90.5 kDa. Due to glycosylation, the protein migrates to 91-115 kDa based on Tris-Bis PAGE result. | Endotoxin : Less than 1EU per ug by the LAL method. | Purity : > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC. | Storage : Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. | Reconstitution : Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
