Used in biomedical research to measure calcitonin levels in rat samples, this ELISA kit enables accurate quantification of calcitonin hormone in serum, plasma, or cell culture supernatants. It is widely applied in endocrinology studies focusing on calcium metabolism, thyroid function, and bone turnover. Researchers use it to evaluate hormonal responses in experimental models of osteoporosis, hypercalcemia, and thyroid diseases. The assay provides high sensitivity and specificity, making it suitable for monitoring changes in calcitonin during drug development and physiological studies.
