| Biological Activity | As a truncated GIP analog, this peptide retains partial activity at the GIP receptor (GIPR) but with reduced affinity compared to full-length GIP (1-42); it stimulates glucose-dependent insulin release (EC₅₀: ~10–50 nM) in human pancreatic β-cell cultures via GIPR-mediated Gαs/cAMP signaling, weakly modulates lipid metabolism by promoting adipose tissue glucose uptake and inhibiting lipolysis in adipocytes, and binds to human GIPR with ~10–100x lower affinity (Ki: ~1–10 μM) than full-length GIP, making it useful for studying GIPR structure-function relationships. |
| Storage Conditions | Store at -20°C in a tightly sealed, light-protected container. Avoid moisture and repeated freeze-thaw cycles. |
| Stock Location | Stock in USA |
| MOQ | 1g |
1.MECHANISM OF ACTION
GIP Receptor (GIPR) Binding: Binds to human GIPR with reduced affinity (Ki: ~1–10 μM) compared to full-length GIP (1-42), primarily interacting with the receptor’s extracellular domain.Glucose-Dependent Signaling: Activates GIPR-mediated Gαs/cAMP signaling in pancreatic β-cells, weakly stimulating insulin secretion (EC₅₀: ~10–50 nM) only when blood glucose is elevated.Metabolic Modulation: Weakly promotes adipose tissue glucose uptake and inhibits lipolysis via GIPR in adipocytes, contributing to lipid homeostasis.
2.PRODUCT INDICATIONS
GIPR Research: Studying receptor-ligand interactions, signal transduction, and structure-function relationships (e.g., mapping binding epitopes).Diabetes Studies: Investigating truncated GIP analogs as potential adjuvants to GLP-1 therapies for type 2 diabetes.Metabolic Disorder Research: Exploring GIP’s role in lipid metabolism, obesity, and energy balance.
3.CLINICAL EFFICACY OF PRODUCT
Insulin Secretion: In human pancreatic β-cell cultures, it increased glucose-stimulated insulin release by 2–3x (10 nM concentration) vs. baseline.Receptor Binding: Bound to human GIPR with ~50x lower affinity than full-length GIP (radioligand binding assays).Metabolic Effects: In human adipocytes, it enhanced glucose uptake by 15–20% and reduced free fatty acid release by 10–15% (1 nM, 24 hours).
