[Histonet] Large vessel endothelium problem

[Gayle Callis]

You did not indicate how you do the paraformaldehyde fixation?  Immersion 
or perfusion?

Vascular perfusion followed by immersion for a few hours may help your 
problem - to ensure the tissue is fixed from the inside out and in 
particular the lumens of your large blood (?) vessels.

You did not give details on what you do with the vessels (opened, etc, 
stretched out) during fixation or processing?
