Product Overview
This rabbit polyclonal antibody detects peptide YY (gene PYY) in human samples and is validated for IHC. The predicted molecular weight is 11.1 kDa.
Peptide YY (PYY) is a gut hormone released from L cells of the distal intestine after meals. Acting mainly through NPY Y2 receptors, it reduces appetite and slows gastric emptying and intestinal transit, which makes it a focus of obesity and energy balance research.

Validated Applications
| IHC (paraffin sections) | 0.5–1 µg/mL |
|---|
Samples with confirmed staining (IHC): human appendicitis 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 citrate buffer (pH 6).
Immunogen
Synthetic peptide from the middle region of human peptide YY/PYY. Sequence identity with the mouse and rat orthologs: 91.7%.
Reactivity Notes
The supplier lists reactivity with human. UniProt places peptide YY in the [Peptide YY]: Secreted.
