Application of fluorescence in situ hybridization (FISH) to clinical material is sometimes limited by sample size. In addition, heterogeneity among slides prepared from a single sample may lead to variation in FISH analyses. Reutilization of material for repeated FISH analyses would help to alleviat

โฆ Synopsis
The feasibility of using the same slide repeatedly for fluorescence in situ hybridization (FISH) experiments was systematically evaluated by applying standard procedures and various combinations of direct-and indirect-labeled probes to slides from patients with hematologic malignancies. Specific and distinct hybridization signals along with weak background signals and chromosome morphology of good to moderate quality could be obtained in up to three experiments performed consecutively on the same slide. Signals related to biotin-or digoxigenin-labeled probes applied in previous hybridizations were still visible with variable intensity, but interpretation problems that may result from this signal noise can be avoided by using adequate probes, detection systems and fluorochromes, and sequence of experiments.
