Dear Cynthia--Laser Capture Microdissection  is a technique that calls for
$50,000+++to set up.  Special protocols for cutting, staqining, fixing,
etc.  The slide is placed on the stage and you "zap" the tissue9where you
want to-only) with a laser while looking thru a  scope.  We do a lot of
tumor slides--and then make "dirty DNA" or RNA from the final tumor cells.
It is extremely interesting and the very CUTTING EDGE of histo.

If I may be of any more help---write--
Sincerely,
Louise
