Polymyxin B Sulfate is an antibiotic that belongs to the polymyxin class of antibiotics and is primarily effective against Gram-negative bacteria.

Polymyxin B is derived from Bacillus polymyxa and acts by disrupting the integrity of the bacterial cell membrane.

In the field of microbiology and cell culture, Polymyxin B Sulfate is commonly used to prevent bacterial contamination. It is particularly effective against Gram-negative bacteria, including multidrug-resistant strains such as Pseudomonas aeruginosa. Researchers add Polymyxin B to growth media or solutions to inhibit the growth of these bacteria and maintain the purity of cultures.

Overall, Polymyxin B Sulfate is a valuable antibiotic in the life science marketplace, primarily used in microbiology, cell culture, and molecular biology research. Its effectiveness against Gram-negative bacteria and multidrug-resistant strains makes it a crucial tool for maintaining sterile cultures and studying bacterial pathogens. However, careful consideration of its potential toxicity is necessary when using it in cell culture applications.
