Used in research settings to measure corticosterone levels in rat biological samples such as serum, plasma, or tissue homogenates. Corticosterone is a key glucocorticoid hormone involved in the stress response, making this ELISA kit essential for studies in neuroendocrinology, behavioral science, and stress physiology. It enables accurate quantification of hormone levels to assess adrenal function, hypothalamic-pituitary-adrenal (HPA) axis activity, and the impact of experimental treatments or environmental stressors in rodent models. The assay is widely applied in pharmacology, toxicology, and neuroscience research where reliable, high-throughput hormone measurement is required.
