Used in research settings to quantify soluble leptin receptor levels in biological samples such as serum, plasma, or cell culture supernatants. This assay helps investigate leptin signaling pathways, which play a key role in regulating appetite, metabolism, and energy balance. The kit is commonly applied in studies related to obesity, metabolic disorders, and endocrine function. It enables high-throughput analysis with high sensitivity and specificity, making it suitable for both clinical research and preclinical studies. Results from this ELISA can provide insights into leptin resistance, a condition often observed in obesity and type 2 diabetes.
