6.9 Conclusions
Cryoembedding in Lowicryl HM-20 preserves both antigenicity and ultrastructure
of brain tissue, enabling conjugate array tomography. Using fluorescence microscopy, dozens of different antibodies and other fluorescent markers can be imaged
at synaptic resolution within large volumes of tissue. The same arrays can also be
viewed using field emission SEM, which allows for the classic benefits of electron
microscopy. Such integration of different imaging modalities can substantially
enrich our understanding of the brain.
