Slide Preparation

Original Protocol from Beliveau et al: File:Slide preparation for interphase FISH.pdf

1. Rinse slides in 100% ethanol; allow slides to dry completely
2. Prepare a cell suspension of 500 000-2 000 000 cells/mL in growth media
3. Add 100 uL of cell suspension per slide roughly in the center
4. Allow cells to adhere for 1-3 hours at the growth temp of the cell line
5. Rinse slides briefly in 1X PBS
6. Fix slides for 5-15 minutes in 4% (v/v) paraformaldehyde in 1X PBS
7. Rinse briefly in 1X PBS in a coplin jar
8. Incubate for 5 minutes in 2X SSCT
9. Incubate for 5 minutes in 2X SSCT + 50% (v/v) formamide
10. Transfer to fresh container of 2X SSCT + 50% (v/v) formamide for storage at 4C
11. Slides are typically best used within 1-2 weeks of creation
