Figure 3. Loss of infectivity is enhanced by OmpA.

In vitro genome ejection of (A) wild type P22, and of two P22 hybrids, one with an Sf6 tail (B) and the other with a T4 “foldon” tail (C). The “fraction of infectious virions remaining” was calculated at each time point as the number of PFU remaining after incubation with LPS, OmpA or LPS and OmpA, divided by the number of PFU when incubated with buffer at t = 0 min.
