Alkali Scientific Amphotericin B 250µg/mL Solution, 20 Milliliters

Amphotericin B is a polyene antifungal agent widely used in cell culture and microbiological applications to control fungal contamination. It targets fungal cell membranes by binding to ergosterol, creating pores that disrupt membrane integrity and lead to cell death. This selective mechanism makes it highly effective against yeasts and molds while minimizing effects on mammalian cells when used at appropriate concentrations. The solution format provides a convenient ready to use antifungal reagent for laboratory workflows. It is commonly added to cell culture media to prevent fungal growth and is widely used in research, pharmaceutical, and diagnostic laboratories where maintaining contamination free conditions is critical.
