CollaPlugs are by Calcitek cat#0102. 2320 Faraday Avenue, Carlsbad, CA 92008
800 854 7019. I haven't bought any for awhile, but the last price I have is
$63/box of 10 which equals 30 cell preps. The only problem with using the
plugs as Gayle describes might be that in the original message the point was
made that the original morphology of the cells needs to be maintained. That
won't happen if you trypsinize the cells off the plates and scraping may
disrupt at least some of the cells so that may be a problem. Some cell
lines, not all, will actually grow into the plug so that's really the best
option if you can setup new cultures.
