Used in biological research to measure thyroid-stimulating hormone (TSH) levels in zebrafish samples. Helps assess thyroid function and endocrine system activity in developmental and toxicological studies. Widely applied in environmental research to evaluate the impact of pollutants, such as endocrine disruptors, on thyroid health in aquatic models. Supports drug development and screening by enabling precise hormone quantification in genetically modified or disease-model zebrafish. Provides a reliable, sensitive tool for high-throughput analysis in laboratory settings studying neuroendocrinology and metabolic regulation.
