Bacitracin Zinc Size:5 g Magnesium chloride is frequently usedBacitracin, is a small cyclic polypeptide that binds to dolichol PP preventing its dephosphorylation to dolichol P, which is needed for building the oligosaccharides including glycolipids required for extracellular cell wall synthesis. Bacitracin is not cell permeable, so even though it has similar activity to tunicamycin on bacteria, it is harmless to eukaryotes cells.
