Application of freeze-etching method to the study of reovirus-infected LLC-MK2 cells
Applied Microbiology
|June 1, 1970
Abstract:
A continuous cell line of rhesus monkey kidney cells, LLC-MK(2), was infected with reovirus type 1 (Lang). The cells were freeze-etched as a method for observing the structural details of the reovirus-induced cytoplasmic inclusion. Information on maturation may be obtained by preparing infected cells for electron microscopy by freeze-etching.
Insights
Freeze-etching electron microscopy reveals structural details of reovirus type 1 cytoplasmic inclusions in LLC-MK(2) cells. This method offers insights into reovirus maturation processes.
