Product Overview
This rabbit polyclonal antibody detects vasoactive intestinal polypeptide receptor 1 (gene VIPR1) in human, mouse and rat samples and is validated for IHC and Western blot. The predicted molecular weight is 51.5 kDa, and the supplier reports an observed band at about 52 kDa.
VPAC1 (VIPR1) is a class B G protein-coupled receptor that binds vasoactive intestinal peptide and PACAP with similar affinity. It signals mainly through Gs to raise cAMP. VPAC1 is found in many tissues, including the gut, lung and immune cells, and is studied in secretion, inflammation and neuroendocrine signaling.

Validated Applications
| Western blot | 0.1–0.5 µg/mL |
|---|---|
| IHC (paraffin sections) | 0.5–1 µg/mL |
Samples with a confirmed band (WB): human A431 cells, human PANC-1 cells.
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, 50 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 1:10000, ECL detection.
Immunogen
Synthetic peptide from the C-terminal region of human VIP Receptor 1. Sequence identity with the mouse and rat orthologs: 84%.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places vasoactive intestinal polypeptide receptor 1 in the cell membrane. Tissue expression noted by UniProt (human): In lung, HT-29 colonic epithelial cells, Raji B-lymphoblasts. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
