inhibition by polymyxin b was stoichiometric , and in repeated experiments , lps was completely suppressed in the hemagglutination assay at a polymyxin b : lps weight ratio of 1:4.1 ( increasing polymyxin concentration , constant lps concentration ) and 1:5.1 ( constant polymyxin concentration , increasing lps concentration ) .
