A method, as shown in the figure, of preparing fluorescent in situ hybridization slides, comprising: providing a slide with a raised ring thereon; providing to the slide a DNA probe; providing to the slide cells and target DNA; providing to the slide a formamide-free mixture of 10 % +/- 2 % by weight dextran sulfate, and 15 %-25 % glycerol and 0.9 % by weight salt or a solution of 10 % +/- 2 % by weight dextran sulfate, 10-30 % by volume formamide and 0.9 % by weight salt; placing a coverglass on the ring; denaturing and hybridizing the slide; and performing a post-hybridization wash of the slide. |
