Fig. 1.
Pictures with both the normal and abnormal patterns for the break-apart and fusion strategies.
In all cases the clonal PCs are identified by the intense blue fluorescence of the cytoplasm as detected by the cIg-FISH procedure. (A) A PC with the normal configuration for the VH (red signal) and CH probes (green signal). Arrows point to the closely associated pairs of signals indicative of a normal pattern. (B) Segregation (break-apart) of the VH (green) and CH (red) probes consistent with a 14q32 translocation. (C) A cell with fusion signals (arrows) resulting from comigration of the pools of probes at 14q32 (green) and 4p16.3 (red) consistent with a t(4;14)(p16.3;q32). (D) The fusion signal (arrows) resulting from comigration of the pools of probes at 14q32 (green) and 16q23 (red) consistent with a t(14;16)(q32;q23).
