It is a white crystalline solid with a melting point of 154-155°C

and lab surfaces (see material compatibility in "INFO")

but dsDNA runs faster with TAE buffer

Its mechanism of action involves physically breaking down the cell walls of microorganisms and inhibiting the synthesis of enzymes required for their reproduction

Polymyxin B sulfate Other Gels toxicity testingDescription Polymyxin B sulfate: Polymyxin B sulfate (PMB) is a strongly cationic cyclic polypeptide antibiotic isolated from fermentation of Bacillus polymyxa. PMB is a variable mixture of B1 and B2 (predominantly B1). Polymyxins combine with cell membranes and disrupt normal permeability to small molecules. Polymyxin B and the other polymyxin antibiotics act primarily by binding membrane phospholipids and disrupting the cytoplasmic membrane,
