Active Recombinant Human DPP4 protein(Asn29-Pro766), hFc-tagged

Specification :
| Source : HEK293 | Species : Human | Tag : N-hFc | Protein length : Asn29-Pro766 | 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 recombinant Cynomolgus CXCL12 in a functional ELISA. 2. Measured by its ability to bind recombinant Human SDF1b in a functional ELISA. 3. Loaded Fc-DPPIV on ProA Biosensor, can bind MERS-CoV Spike/RBD Protein fragment (RBD, aa 367-606, His Tag) with an affinity constant of 1.04 nM as determined by Octet RED System. 4. Loaded Fc-DPPIV on ProA Biosensor, can bind MERS-CoV Spike/S1 Protein (S1 Subunit, aa 1-725, His Tag) with an affinity constant of 0.02 nM as determined by Octet RED System. 5. Loaded Fc-DPPIV on ProA Biosensor, can bind MERS-CoV Spike/RBD Protein fragment (RBD, aa 367-606, His Tag) with an affinity constant of 1.04 nM as determined by Octet RED System. 6. Loaded Fc-DPPIV on ProA Biosensor, can bind MERS-CoV Spike/S1 Protein (S1 Subunit, aa 1-725, His Tag) with an affinity constant of 0.02 nM as determined by Octet RED System. | Molecular Mass : The recombinant human Fc/DPPIV is a disulfide-linked homodimeric protein.The reduced monomer consists of 975 amino acids and has a predicted molecular mass of 112 kDa. As a result of glycosylation, the apparent molecular mass of rhFc/DPPIV monomer is approximately 120-130 kDa in SDS-PAGE under reducing conditions. | Endotoxin : | 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.
