Flow Cytometric Immunobead Assay for Detection of BCR-ABL1 Fusion Proteins in Chronic Myleoid Leukemia: Comparison with FISH and PCR Techniques..     ///    "Currently, measurement of BCR-ABL1 mRNA transcript levels by real-time quantitative PCR (RQ-PCR) defines critical response endpoints. "    ///    The resulting BCR-ABL1 oncogene leads to increased proliferation and survival of leukemic cells.     ///    "Here we describe a flow-cytometry assay that detects the presence of BCR-ABL1 fusion proteins in CML lysates to determine the applicability, reliability, and specificity of this method for both diagnosis and monitoring of CML patients for initial response to therapy. "    ///    An antibody-based technique for BCR-ABL1 protein recognition could be an attractive alternative to RQ-PCR.
