Goat LEP (Leptin) ELISA Kit (GTFI00033)

The Assay Genie leptin immunoassay enables quantitative measurement of LEP in caprine serum or plasma specimens, supporting laboratories studying energy homeostasis, adipokine signaling, and reproductive physiology in small ruminants. Leptin, the 16 kDa peptide hormone encoded by the LEP gene and secreted predominantly by white adipose tissue, communicates peripheral energy stores to the hypothalamus and influences appetite, thermogenesis, and gonadal function. In goat research models, circulating leptin concentrations serve as a biomarker for body condition score, nutritional plane, puberty onset, and seasonal reproductive cyclicity, making a reliable quantitative assay essential for both field investigations and controlled feeding trials.

Each kit is supplied in a 96 Assays format and includes all reagents required to run a full microplate, such as pre-coated wells, detection antibody, calibrator standards, and substrate solution. Researchers should store the unopened kit refrigerated and avoid repeated freeze-thaw cycles of individual components; reconstituted standards and diluted samples are best aliquoted and frozen for single use to preserve immunoreactivity. The assay is intended for in vitro research use only and is validated for goat samples, while laboratories working with related species such as sheep may evaluate cross-reactivity empirically.

Common applications include profiling circulating leptin across lactation stages in dairy goats, monitoring nutritional recovery in kids after weaning, correlating LEP concentrations with ovarian follicle dynamics during the breeding season, and assessing metabolic responses to dietary manipulation in meat goats. The kit integrates into standard immunoassay workflows using a plate reader capable of colorimetric readout, and the included protocol recommends appropriate dilution of high-concentration specimens to remain within the assay working range.
