Used in biomedical research to measure soluble leptin receptor levels in biological samples such as serum, plasma, or cell culture supernatants. Helps in studying leptin signaling pathways, which play a key role in regulating appetite, body weight, and energy balance. Commonly applied in obesity, metabolic syndrome, and diabetes research to understand how leptin resistance develops. Also useful in investigating inflammatory conditions and hormonal disorders where leptin metabolism is altered. The kit enables sensitive and specific detection, supporting high-throughput analysis in preclinical studies.
