Used in bone metabolism studies to measure β-isomerized C-terminal telopeptide of type I collagen (β-CTx), a key biomarker of bone resorption. This ELISA kit is specifically designed for research use to quantify osteoclast activity in rat samples, making it valuable in preclinical studies of osteoporosis, arthritis, and other bone-related diseases. It enables researchers to assess the effectiveness of therapeutic agents targeting bone loss by providing a sensitive and specific measurement of collagen breakdown products in serum or plasma. Commonly used in pharmaceutical development and academic research involving animal models of bone disease.
