| Abstract: | Methods for mounting and staining relatively thin sections on electron microscope grids, in order that one and the same section of a cell can be photographed in sequence with the light and electron microscope are described. Toluidine blue is used as a stain and hexachlorabuta-1,3 diene as a medium which enables the grid carrying the stained sections to be temporarily mounted under a coverslip and examined with an oil-immersion lens. Results obtained with pollen mother cells of Fritillaria lanceolata at zygotene are illustrated. |
