Alkali Scientific Amphotericin B, 5 G

Amphotericin B is a polyene antifungal agent widely used in laboratory research to prevent fungal contamination in cell culture and microbiological studies. It interacts with ergosterol in fungal membranes, creating pores that disrupt membrane integrity and result in cell death. This makes it highly effective against a broad range of fungi. In laboratory workflows, it is commonly used to maintain sterile culture environments and protect experimental samples from fungal overgrowth. Amphotericin B is also employed in antifungal susceptibility testing and research focused on fungal biology, providing consistent and reliable antifungal activity.
