Leukemic samples from patients P30 and P52 wereEcoRI digested, size fractionated on 1% agarose gel, and hybridized with the following probes: (A) control probe bcl-1; (B) probe p6E3.2, with densitometry results of 0.52 in patient sample P30 compared with the P52, which had no loss detected with any 13q14 probe, showing hemizygous loss for P30; and (C) probe P9.19, which recognizes a 19 EcoRI band present in cosmid C9a, with densitometry results of 0.02 for the P30 sample compared with the P52 sample, showing homozygous loss for P30.
