We have developed a simple, rapid, sensitive bioassay for megakaryocyte growth and development factor (MGDF) or thrombopoietin (TPO) based on its ability to stimulate the proliferation of the human megakaryoblastic cell line MO7e. The bioassay takes only 24 h, is reproducible and sensitive to less than 10 pg/ml of MGDF. It can be made specific for MGDF by including neutralizing antibodies specific for MGDF, and is suitable for detection of MGDF in both plasma and serum samples.
