Used for the quantitative measurement of thrombopoietin (TPO) levels in human serum, plasma, or cell culture samples. This ELISA kit helps in researching blood disorders related to platelet production, such as thrombocytopenia and myeloproliferative neoplasms. It is also useful in clinical studies assessing bone marrow function and immune response regulation. The assay enables high sensitivity and specificity, making it suitable for both diagnostic research and drug development involving TPO receptor agonists.
