Lets imagine that I have mammalian cells that I've immobilized on a filter. Now I want to keep providing small molecules to these immobilized cells without resolubilizing the cells.

The caveat is that I would like to do so without fixing the cells or waiting for them to adhere to the filter. The small molecules are small enough to diffuse through the filter.

perhaps you can dip the filter plate in a medium containing the small molecules.. and then keep changing the bath after few days.. btw you want a batch or continuous system?? –  WYSIWYG Jun 10 '13 at 7:55
    
@WYSIWYG, Batch should be fine. The question is what would be the setup to do so. Would it be as simple as reversing a 96 well lid over and placing the filter plate on top? What about the wetting? –  bobthejoe Jun 10 '13 at 22:46
    
I am not very sure but you may try the plates used for growing ES cells over feeder layers separated by a membrane –  WYSIWYG Jun 11 '13 at 4:38

Perhaps you're looking for these hanging inserts, for example: "Millicells"
