Dipeptidyl-Peptidase 4 (DPP4), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in protein studies such as protein structure analysis and protein-protein interactions. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.

This recombinant protein was expressed from a DNA sequence encoding the extracellular domain (Asn 29-Pro 766) of the mature form of human DPP4 (NP_001926.2) fused to the fused Fc region of human IgG1 at the N-terminus.

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.

Formulation: Lyophilized in 140 mM NaCl, 2.7 mM KCl, 10 mM Na₂HPO₄, 1.8 mM KH₂PO₄, pH7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 25 µg/ µl or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: Expires one year from date of receipt when stored as instructed.

This protein is manufactured by SINO Biological.
