Product Information

• Name: Polymyxin B1-I
• Brand: Biosynth
• Description: Polymyxin B1-I is an antimicrobial peptide, which is sourced from the bacterium *Bacillus polymyxa*. It functions by interacting with and disrupting the bacterial cell membranes. The polypeptide inserts into the phospholipid bilayer, causing increased permeability and eventual cell lysis. This mechanism is particularly effective against Gram-negative bacteria due to the structural composition of their outer membranes.
