Method for the removal of selected cells from cytological smear preparations for transmission electron microscopy
Abstract:
The method described depends on fixing additional cytology smear preparations with glutaraldehyde to be used, if needed. Removal of cells from the slide makes use of partially polymerised resins in the usual way but a paper marker is used to localise the area in the resin block which contains the cells to be examined. Slides are placed in a freezing cabinet to facilitate easy separation of the resin block.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
