Preparation of samples for TEM analysis
A solution of isolated M13 bacteriophage (20 μL) was adsorbed onto a 300-mesh carbon-coated copper grid (AGS160-3) for two minutes. The grid was then stained with 2% uranyl acetate before TEM analysis. A Zeiss - EM10C - 80 KV transmission electron microscope was used for visualizing the prepared samples.
