They are called Chamber Slides and Falcon makes them.

Hi All
I have seen a system that allows you to grow cells directly on glass slides
.  I do not know the name of  the system since I have never actually used
for cell culture but do have a collaborator who use it exclusively.
Essentially,  It is a clear plastic box without bottom that fits over the
glass slide (excluding the label area).  A "rubber?" contact adhesive is
used(do not know name or composition) to attach the box to the slide surface
such that a water tight seal is made. The box comes with a lid and the cells
can be grown directly on the glass slide. The benefits of this system are
that any fixative can be used.  Also,  if you are doing manual staining,
the adhesive acts as a hydrophobic barrier so you do not have to use a PAP
pen.  The main drawback is if your are doing automated staining.  You have
to scrape the adhesive off the slide for cap gap instruments or ventana
instruments because it will impeded the movement/mixing of solutions.  In
addition,  the entire slide is covered with cells so it would require a lot
of reagent when doing manual staining, we have gone around this by wiping of
areas of the slide Ill see if I can come up with a name.
Thought this might be another option (although the lack of vendor
information  makes it this post quite useless :-)
Regards
Luis

Hi Laura,
In the past I did some IHC on cell cultures grown on plastic disposables.
This created an extra problem with respect to the fixation since
acetone-fixation was not possible for obvious reasons. Finally, we used a
4% paraformaldehyde (freshly prepared in PBS) for 5 min at RT. This short
aldehyde-fixation does not cause any cross-linking and therefore antigen
retrieval is not needed (impossible too, because of the plastics!)
During ALL IHC incubation steps and washings (from endo PO blocking up to
chromogen) we included 0.1% saponin to open up the cell membranes (to get
your IHC reagents in and out of the cells).
Lots of success!
