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 S1, with a length of 129.2 ± 1.3 nm and a width of 9.93 ± 0.66 nm, is remarkable for its extreme flexibility, compared with the tail of S4 (201.87 ± 1.22 nm long and 10.7 ± 0.24 nm wide).
