Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Description

Gastric inhibitory polypeptide receptor plays a central role in glucose homeostasis and energy metabolism, making its extracellular domain a key target for therapeutic antibody development in obesity and metabolic disease research. This partial construct spanning residues 19–134 captures the ligand-binding region and demonstrates quantifiable binding activity in functional ELISA, where immobilized protein at 2 μg/mL binds an anti-Gipr recombinant antibody with an EC50 of 8.622–11.36 ng/mL—a result that supports its use in competitive inhibition assays, blocking antibody screening, and therapeutic antibody epitope mapping. Mammalian expression preserves native glycosylation and disulfide bond formation critical for conformational integrity in receptor-ligand interaction studies, including surface plasmon resonance and biolayer interferometry experiments. The protein meets quality thresholds commonly required for drug discovery applications, with greater than 95% purity by SDS-PAGE and endotoxin levels below 1.0 EU/μg, providing a suitable basis for small-molecule or biologic inhibitor screening platforms.

Target Background

Function

This is a receptor for GIP. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase.
