QMPSF assay in DLBCL. (A) Gene copy number abnormality distribution in diffuse large B-cell lymphoma (DLBCL; n = 114). (B) Example of an electropherogam obtained from the quantitative multiplex PCR of short fragments (QMPSF) assay. Tumor and normal QMPSF electropherograms are indicated in blue and orange, respectively. Amplicons are identified according to their expected sizes (x-axis). The heights of the peak (fluorescence; y-axis) are proportional to the amount of corresponding target DNA.
