The use of negatve staining method for viral and bacterial diagnostics using the transmission electron microscope.
ŠOBEROVÁ, Tereza
This bachelor thesis is focused on the negative staining method used in making diagnosis of viruses and bacteria in the transmission electrom microscope (TEM). Theoretical part provides general description of TEM, negative staining method and basic characteristics of viruses used in this project. Detailed description of procedure designed for the preparation of specimens is the key part of this project. After their display in TEM, the testis analyses the quality of virus images and comparison of effects of the most common staining agents, pH, trehalose and different times of staining on displaying the ultrastructure of biological specimens and on the size of individual viral particles. The conclusion of project contains staining agents providing the best imaging of objects that have been selected based on the evaluated results and recommendations for potential enhancement of staining properties in other agents.
