Used for measuring bone-specific alkaline phosphatase (BALP) levels in rat biological samples such as serum or plasma. This ELISA kit is specifically designed to assess bone formation activity in preclinical research. It is commonly applied in studies related to osteoporosis, bone regeneration, and metabolic bone diseases. The kit enables researchers to quantify BALP with high sensitivity and specificity, supporting evaluation of drug efficacy, toxicity, or hormonal effects on bone metabolism in rat models.
