General description
Chemical structure: peptide
Application
Polymyxin B sulfate is a strongly cationic cyclic polypeptide antibiotic that is derived from fermentation of Bacilus polymyxa. It is a mixture of B1 and B2 sulfate. The product has been used clinically to treat infections of the urinary tract, meninges and blood stream caused by susceptible strains of Pseudomonas aeruginosa. It also has uses studying multidrug-resistant pathogens, as an immobilized agent for removal of endotoxins, and to induce pore formation in the membranes of cortex cells from excised sorghum roots.
Biochem/physiol Actions
Mode of Action: Polymyxin B Sulfate binds to the lipid A portion of bacterial lipopolysaccharides†, disrupting the cytoplasmic membrane by inducing pores large enough to permit nucleotide leakage in bacterial walls. This disrupts the permeability of the cytoplasmic membrane.
Antimicrobial spectrum: Has bactericidal action on most gram-negative bacilli††, including E. Coli and on most fungi and gram-positive bacteria.
Antimicrobial spectrum: Has bactericidal action on most gram-negative bacilli††, including E. Coli and on most fungi and gram-positive bacteria.

I see that you list several Polymyxin B Sulfate products (P0972, P1004, P4932, 81334 and P4119). What are the differences?
1 answer-
The primary difference between the products is the testing. Product P0972 is USP tested, product P4932 is tested against 3 mammalian cell lines to make sure it is not toxic to the cells, product P4119 is cell culture and endotoxin tested, and products P1004 and 81334 are the research grades with P1004 in USP units and 81334 in international units.
