title: [Method of preparing suspended cells for scanning electron microscopy].
abstract: To preserve the lifetime morphology of the surface of suspended cells, these must be fixed in suspensions. The subsequent stages of cell preparation for scanning electron microscopy (dehydratation, critical point drying, coating) are considerably facilitated if fixed cells are preliminary attached to some substrate surface. An effective substrate should provide a firm rather than selective attachment of the overwhelming majority of fixed cells; the substrate should be also available for a wide application. The trial of different types of substrates showed a sufficient effectivity of plates made of commercial aluminium foil. In tests with murine embryonal and transformed fibroblasts as well as with human blood leukocytes, in average 90 per cent of cells fixed with glutaraldehyde in suspensions got attached to foil substrate surfaces; the fixed cells both settled from suspension and attached were seen distributed evenly on the substrate surface. The use of aluminium foil substrates made it possible to study the surface topography of some types of suspended cells.
