File talk:HeLa cells stained with Hoechst 33258.jpg

I'm looking for a high res. (350 dpi. tiff) of a stained HeLa cell for a book on ethics, bieothics, medical practice, etc. The one on the page is great but...not high enough resolution. Can you help? Email either at my wiki acct. or tomkoch@kochworks.com with suggestions. And ...thanks. TK.
