From: Proteomic analysis reveals heat shock protein 70 has a key role in polycythemia Vera
Flow chart describing the three-steps to proteomic screening for differentially expressed proteins in polycythemia vera (PV) and essential thrombocythemia (ET). The training set includes two-dimensional difference gel electrophoresis (2D-DIGE) and mass spectrometry (MS); the protein validation set includes immunohistochemistry (IHC); and the functional validation set includes burst formation unit-erythroid (BFU-E) and stem cells studies.
