Rat PYY PharmaGenie ELISA Kit (SBRS0157)

Built around a competitive immunoassay principle, this microplate kit from Assay Genie quantifies Peptide YY (PYY), a 36-amino acid satiety hormone secreted by L-cells in the distal ileum and colon after feeding. In the workflow, PYY in the test sample competes with a conjugated reference for binding on pre-coated wells, so higher analyte concentration yields a lower colorimetric signal.

Validated for rat serum and cell culture supernatant matrices, the reagents support in vitro research on appetite regulation, energy homeostasis, and gut-brain signaling, including post-bariatric and high-fat-diet intervention studies. Each 96-assay pack is supplied with a foil pouch of plate strips, lyophilized peptide standard, biotinylated detection antibody, wash buffer concentrate, streptavidin-HRP conjugate, chromogenic substrate, and stop solution; store unopened components at 4 degrees C protected from light and equilibrate to room temperature before use.
