Results indicate that the addition of CaCl2 to suspensions of the Mg-bound R-form LPS result in a tighter binding of Ca2+ to the R-form LPS and the release of Mg2+ from the R-form LPS, and as a consequence, destroys the Mg2+ -induced ordered hexagonal lattice structure of the R-form LPS

Also, binding of dansyl-polymyxin to P. cepacia ( and P. aeruginosa ) LPS was inhibited by polymyxin B, streptomycin, gentamicin, and Mg2+
