Used in biological and toxicological research to measure cortisol levels in zebrafish, this ELISA kit enables assessment of stress responses in aquatic models. It is widely applied in environmental studies to evaluate the impact of pollutants, drugs, or changing water conditions on fish physiology. Researchers also use it in behavioral studies and neuroendocrinology to link stress hormone levels with developmental, genetic, or pharmacological interventions. The kit supports high-throughput, quantitative analysis, making it valuable for laboratory experiments requiring reliable and sensitive hormone detection.
