[Histonet] IF on cell lines

This may not be useful to your colleague at all, but here goes: I used
to place a round glass sterile coverslip in the bottom of each well of a
24-well culture plate before seeding and then grew the cells on the
coverslip. When ready the coverslip was removed (using a hyperdermic
needle with the bevelled tip bent backwards to catch the edge of the
cs). The coverslips were then picked up with "eyelash" forceps and
placed in a little porcelain coverslip rack and placed in cold acetone
(-20 C) to fix for 10 mins. Following IF staining the round coverslip
was mounted on a regular coverslip which was in turn mounted on a glass
slide for viewing.
In case you haven't already figured this out, acetone melts the plastic
chamber slides. My coverslip method, while effective, is obviously much
more laborious (which I suppose is why the chamber slide was developed
in the first place! LOL). Hopefully the 4% paraform. works. Is methanol
fixation an option??

I have a colleague who is trying to do IF on cell culture cell lines.
is growing them on cell culture treated chamber slides and fixing with
formaldehyde. Her problem is that after fixation and a few washes all
cells are detaching. Any suggestions? I think she is going to try 4%
paraformaldehyde first as someone has already switching to that.
