Used in research settings to quantify preptin levels in biological samples such as serum or plasma. Preptin is a peptide involved in bone metabolism and insulin secretion, making this kit valuable for studies related to diabetes, osteoporosis, and metabolic disorders. The ELISA format allows for high sensitivity and specificity, enabling researchers to monitor changes in preptin concentration under various experimental or clinical conditions. It supports investigation into the role of preptin as a potential biomarker for metabolic and bone-related diseases.
