RPI Polymixin B SuLfate, 5 Grams

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.
