Product Overview
This rabbit polyclonal antibody targets gastric inhibitory polypeptide (gene Gip) in mouse and rat samples and is validated for IHC and Western blot. The predicted molecular weight is 16.4 kDa, and the supplier reports an observed band at about 18 kDa.
Gastric inhibitory polypeptide (GIP), also called glucose-dependent insulinotropic polypeptide, is an incretin hormone released from K cells of the upper small intestine after meals. It acts on pancreatic beta cells to boost insulin secretion when glucose is elevated, and it has only a weak effect on gastric acid, so it is widely studied in glucose and metabolic regulation.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Mouse) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Mouse, Rat) |
Samples with a confirmed band (WB): mouse stomach tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): mouse colon tissue, rat colon tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Recombinant mouse GIP fragment (Tyr44–Gln85), expressed in E. coli. Sequence identity with the human and rat orthologs: 92.9%.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt describes gastric inhibitory polypeptide as a secreted protein. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
