Hello Histonetters,
I have been asked about the use of PEG cells and the idea of conjugating
with a nano[-article.
In sort the goals:
1-visualize PEG

3 - functionalized PEG - attach nanoparticles to either induce cell
infiltration or no clots

Were these small pieces of tissue? If they are in an agar (such as

agar is completely dehydrated during processing. The sample, no matter how
small, is protected and processes perfectly. IF you ran a short run wit

For sections that thick you would collect them as you always have, stain
them as floating sections and then mount onto a glass slide. The routine
