[Histonet] culture on coverslips troubles

Linda,
When an investigator requests this we dip our coverslips in a 
chrome-alum-gelatin mixture and let them dry then pick up frozen sections 
on the coverslips. We use it for slides as well sometimes.

10 gm           Gelatin
1000 ml         D. H2O
5 gm            Chromium Potassium Sulfate
optional - few crystals of Thymol
Dissolve the gelatin in hot distilled water - not boiling.
Cool and dissolve the Chromium Potassium Sulfate in the gelatin mixture. A 
magnetic stirrer is helpful.
Add a few crystals of thymol if you want.
Store at RT in clean bottles. If you put it in the refrigerator the gelatin 
will harden (duh!).

Make sure your coverslips are clean, clean, clean. Drain on paper toweling 
and allow to air dry. Store them in a dust free box when dry.

Wear gloves - this is a possible carcinogen.

You might be able to use a Poly-L-lysine Solution too. Got mine from Sigma 
and dilute it 1ml to 10 in D. H2O.
