詳細

Polymyxin B is a polypeptide antibacterial that belongs to the polymyxin family. It exerts its effects against Gram-negative bacteria such as Pseudomonas aeruginosa, Acinetobacter baumannii, Enterobacter sp., and Klebsiella sp.. Polymyxin B sulfate is a mixture of polymyxin B1 sulfate and polymyxin B2 sulfate.

アプリケーション

Polymyxin B Sulfate - CAS 1405-20-5 – Calbiochem has been used:
  • to neutralize the endotoxins in bovine serum albumin
  • in the in vitro treatment of hepatic stellate cells (HSCs)
  • as an antibiotic in collateral sensitivity and cross-resistance analysis in Escherichia coli

生物化学的/生理学的作用

Polymyxin B possesses antiendotoxin activity. It binds to lipid A of the lipopolysaccharide (LPS) molecules and facilitates penetration by displacing Ca2+ and Mg2+ in the outer membrane of Gram-negative bacteria.
