RE:Air Drying of plates before staining...
Yongzhong Wang and interested others:
In our experience, if plates are not air dried prior to fixation and again prior to staining, cells detach from the plate leaving you nothing to stain. This may merely be a peculiarity of our bone cell cultures. Our osteoblast precursor cell cultures (CFU-F) are much more adherent and less likely to float away. Osteoclast cells however, are not inclined to stick to the plastic dishes. They much prefer bone slices. Staining bone slices is rather straightforward. You'll have to experiment with your particular cells to see if air drying is needed and where. Our entire procedure manual is rather long, but I'm having it converted into a PDF file and placed on our website. When that process is complete, I'll inform the histonet ether. In the meanwhile, I can email pertinent portions to interested parties as a word document.

Would you please send me the procedure by email? Right now I am doing
something similar and an having some problems in my staining. I don't
understand why you need to air dry completely before fixation and before
staining. Will the cells still be intact that way?
