Re: coverslips for In-situ staining

From:Mikael Niku

You don't need any special kind of coverslips. We are
routinely doing ISH with standard glass coverslips, and
it's working perfectly.

Briefly:
- Apply hybridization solution (100 ul/slide) on
  dehydrated and air-dried slides
- Place the (ethanol-rinsed and air-dried) coverslips
  on the slides, avoiding air bubbles
- Place the slides in a preheated oven (we are using an
  oven with a removable metal tray) for denaturation
  (we are doing genomic in situ hybridization to tissues,
  so the denaturation is pretty harsh - 85 C, 8 min)
- Place the slides in airtight containers, with a bit
  of tissue paper moistened with base constituents of
  the hyb buffer
- Incubate

We are using a standard home-made hybridization buffer
(containing formamide, SSPE, Denhardt's, and ssDNA). No
problems with drying, with hybridization times up to two days. There
is a noticeable amount of vapors in the oven when we open
it, so some of the buffer is evaporating, but not too much.
Probably a good idea to avoid extensive exposure to the
formamide-containing vapors, though.
