Used in biomedical research to measure levels of Gastrin Releasing Peptide (GRP) in rat samples, this ELISA kit enables accurate quantification of GRP in plasma, serum, or tissue homogenates. It is widely applied in studies related to gastrointestinal function, appetite regulation, and neuroendocrine signaling. Researchers also use it to investigate the role of GRP in stress responses, circadian rhythms, and respiratory control in rodent models. The assay supports high sensitivity and specificity, making it suitable for detecting low concentrations of GRP in small sample volumes. It is a valuable tool in preclinical studies exploring peptide hormone dynamics and related physiological pathways.
