polymyxin B2 BiologicalActivity

Description	Polymyxin B is an antibiotic. Polymyxin B inhibits Gram-negative infections by binding to the LPS of the bacterial wall with high affinity. Polymyxin B neutralizes the effect of endotoxin. Polymyxin B induces bacterial death by increasing its permeability. Polymyxin B is used in endotoxemia research[1][3].
