This research kit is designed for the quantitative determination of hormones and signaling molecules derived from endocrine glands in rats. It is widely used in biomedical and pharmacological studies to measure hormone levels such as insulin, cortisol, thyroid hormones, prolactin, and growth hormone in tissue extracts or serum samples. The kit enables researchers to investigate endocrine function, evaluate the impact of drugs or environmental factors on hormonal regulation, and study disease models like diabetes, stress response, and metabolic disorders. Due to its high sensitivity and specificity, it supports accurate detection of low-concentration analytes, making it valuable in longitudinal studies of endocrine dynamics and neuroendocrine interactions.
