Sample #29 Colon tumor

Overview (first microtome cut of 70 consecutive cuts).

Overview CC

 

The sample was mounted and cut in a cryotome.  70 microtome slices, of 12 μm thickness were cut from the tissue. Every 5th cut was placed on membrane suitable for laser capture microdissection (LCMD), the 4 slices in between were placed on glass slides. A grid of 96 (~25000 μm2) circles was used as a template for the laser capture microdissection on each membrane slide. Pictures of slices and LCMD cuts can be found at the following link.
