Transmission electron micrograph of JC1. High titer CsCl gradient purified JC1 virions were stained with 4% uranyl acetate on a copper grid and viewed at 140,000× magnification with a transmission electron microscope. Measurements of 10 phage particles have an average capsid diameter of 71 nm ± 1.24 nm and a short, noncontractile tail measuring 20 nm ± 0.91 nm in length and 13 nm ± 0.67 nm in width. Scale bar represents 100 nm.
