Do anyone know if there is a Electron microscopy facility offering SEM for Exosome ? We have exosome isolated from serum and want to visualize it through SEM.
Exosomes are classically better observed with a TEM either after negative contrast with classical TEM (what I did several times) or after freeze-plunging with cryo-TEM.
If you go with SEM, you should use an FESEM (SEM with field emission gun, which give better resolution).
