SDS-PAGE analysis of LOS expressed by N. gonorrhoeae strain F62 and its derivatives. LOS was isolated by the method of Hitchcock and Brown (reference 37), and analyzed on 16% acrylamide gels using the Tris-tricine buffering system (reference 40). The lanes represent LOS isolated from strain: 1, F62; 2, F62ΔlgtD; 3, F62ΔlgtA; 4, F62ΔlgtAlgtG+; 5, F62ΔlgtAlgtC+; and 6, F62ΔlgtAΔlgtE.
