Division 5.1.5 F1

Spot 16 µl of the fixed suspensions onto a clean multitest slide as shown in Fig. 3. Apply two different samples per slide, undiluted and use 10 µl to make a 1:100 dilution (in 0,01M PB). The remaining sample solution (49 µl) can be stored at -20  °C after addition of 1 volume of 96 % ethanol. In case the FISH assay requires repeating, remove the ethanol by centrifugation and add an equal volume of 0,01M PB (mix by vortexing).
