Phage gradient drops were placed onto 0.022-µm-pore-diameter filters floating on SM buffer at room temperature for 30 min (with two changes of buffer) to eliminate CsCl. Aliquots were negatively stained with 2% (wt/vol) uranyl acetate on copper grids covered with a film of carbon and ionized. Grids were observed with a JEOL 1200 EXII microscope stabilized at 100 KV. Images were obtained on Scientia photographic plates (AGFA).
||Mean+-standard deviation. The tail of S3 is 136.9 ± 0.59 nm by 21.43 ± 0.0 nm and has a basal plate with protruding spikes.
