numbers of integrated DNA have to be detected e.g. by techniques like in-situ hybridization [6]. The sensitivity of isotopic techniques also provides an advantage where a small minority of strains has to be detected e.g. a small percentage of resistant mutants in a large population of susceptible wild type strains [7].

details of the non-isotopic in situ hybridization and the tyramide-me-diated signal amplification, as well as the methods used for acquiring digital images, have been described earlier (6, 7). Following the manu-facturer s protocol (Roche Applied Science), digoxigenin-labeled anti-sense and sense riboprobes were generated from a DNA template con-

technique allows investigators to obtain highly specific information about individual cells. To enhance specificity, Fluorescence In Situ Hybridization (FISH) is used. It is a molecular cytogenetic method that applies fluorescent probes that combines with just those parts of a nucleic acid sequence with a high degree of sequence complementarity.

Recognition and hybridization with the nucleic acid target sequence in the iMS probe s immediate vicinity result in displacement of the placeholder sequence, followed by a stem-loop closure, which brings the Raman dye close to the metal nanoparticle, thus producing a strong SERS signal (bottom, On state).

ous non-isotopic probe labels have also been used, usu-ally detected with immunoenzymatic methods [3] or fluorescent in situ hybridization (FISH) [4,5]. In order to generate sufficient signal, non-isotopic ISH methods usu-ally use long probes or multiple probe cocktails for bind-ing of sufficient number of label molecules to each target.

non-isotopic detection of specific sequences in the nucleus was already apparent by 1982 (Manuelidis et al. 1982). Additional methods for tagging DNA and RNA led to many applications, but the most for delineating interphiLse chromosome structure are three-dimensional (3D) preservation, and the use of
