A novel fluorescence detection method for in situ hybridization, based on the alkaline phosphatase-fast red reactionEJ Speel, B Schutte, J Wiegant, FC Ramaekers and AH Hopman Department of Molecular Cell Biology and Genetics, University of Limburg, Maastricht, The Netherlands. We have used naphthol-ASMX-phosphate and Fast Red TR in combination with alkaline phosphatase (APase) to produce fluorescent precipitated reaction products in a non-radioactive in situ hybridization (ISH) method. To obtain optimal and discrete localization of the strongly red fluorescent ISH signals, the enzyme precipitation procedure was optimized. The optimal reaction time and the concentrations of substrate and capture agent were determined. Furthermore, polyvinyl alcohol (PVA) was used to increase the viscosity of the reaction mixture and thus to reduce diffusion of the reaction product. Our results show that the APase-Fast Red detection method has at least the same sensitivity as currently observed in other immunofluorescent detection systems. A single copy DNA sequence of 15.8 KB could be localized with high efficiency in metaphase spreads and in interphase nuclei. Double labeling procedures, in which the FITC- and azo-dye fluorescence are combined, are also feasible. The red fluorescent ISH signals showed hardly any fading as compared with FITC fluorescence on exposure to either light from the mercury-arc lamp or laser light. Therefore, these red fluorescent signals with a virtually permanent character allow a better analysis and three-dimensional localization of such cytochemically detected genomic fractions by means of confocal scanning laser microscopy as compared with the use of FITC, TRITC, or Texas Red as label.
