Experimentally determined inhibition constants (K_i) of polymyxin B when titrated against 3 different species of LPS. Data are presented as mean ± coefficient of variation (CV), (n = 3).

LPS species	K_i (µM) ± CV
Klebsiella pneumoniae	6.2 ± 33%
Pseudomonas aeruginosa	7.2 ± 30%
Salmonella enterica (typhimurium)	0.95 ± 13%
