Rat NPW23 PharmaGenie ELISA Kit (SBRS0144)

This competitive immunoassay from Assay Genie is configured to quantitate Neuropeptide W-23 (NPW23) in rat-derived matrices. NPW23 is a 23-amino-acid amidated peptide ligand for the GPR7 and GPR8 receptors and has been studied in relation to feeding behavior, energy homeostasis, and hypothalamic-pituitary signaling, making it a useful analyte for neuroendocrine and metabolic research programs.

The kit is supplied in a 96 assays format and is validated for use with cell culture supernatants, plasma, and serum-derived specimens from rat sources. Researchers commonly apply the assay to conditioned media from hypothalamic explants, perfusate from brain slice preparations, or circulating samples to track NPW23 dynamics in vivo and in vitro. The competitive ELISA format is well matched to small peptide analytes where sandwich-style capture is not feasible.

Each kit ships with a pre-coated microplate and the reagents required to process a full plate. A serial dilution of calibrators is included so that sample concentrations can be interpolated from the standard curve. Because NPW23 abundance in circulation is typically low, sample collection, protease inhibitor handling, and storage steps should follow the package insert to preserve peptide integrity before the extraction step. For research use only.
