I4m setting up an endothelial capillary culture system for microscopy according to Cooke 1993. Does any one know where to find flat glass capillaries with an optical quality suitable for high res microscopy ? Any suggestions are welcome. Does any one have experience of such culture systems ? ============================================= Mikael Gustafsson MD, PhD Dept Med.
