Used in biomedical research to detect and quantify thrombopoietin (TPO) levels in human serum or plasma samples. Enables study of thrombopoiesis and megakaryocyte regulation. Commonly applied in diagnosing and monitoring blood disorders such as thrombocytopenia and myeloproliferative neoplasms. Supports clinical research on platelet production and bone marrow function. Provides high sensitivity and specificity for accurate measurement in small sample volumes.
