Hematologic malignancies often have specific chromosomal translocations that promote cancer initiation and progression. Translocation identification is often vital in the diagnosis, prognosis, and treatment of malignancies. A variety of methods including metaphase cytogenetics, in situ hybridization, microarray techniques, Southern blotting, and many variations of PCR are used to identify translocations. While all these techniques have utility, many have drawbacks limiting their clinical usefulness: high cost, slow turnaround time, low density, large sample requirements, high complexity, and difficult validation and standardization. Multiplexed RT-PCR combined with liquid bead array detection overcomes many of these limitations, allowing simultaneous amplification and detection of multiple translocations within one patient sample. This system has high reliability, reproducibility, and flexibility; low cost and low complexity; rapid turnaround time; and appropriate analyte density. Recently, Asuragen Inc. has developed a multiplexed RT-PCR liquid bead array panel that simultaneously analyzes 12 fusion transcripts found in four major types of hematologic malignancies, allowing rapid and efficient diagnosis. In this chapter, we review liquid bead array technology in relation to the specific hematologic translocations analyzed in the Signature LTx panel.
