    Nystatin

    $23.99 - $90.07

    Nystatin is a fungicidal and fungistatic polyene antifungal and growth promoter.  It functions by accumulating cholesterol and thereby sequesters lipid from cell membranes.  It can be used in quantum dot research, since cholesterol depletion could block several lipid raft-dependent endocytic pathways.

    Mechanism of ActionNystatin binds ergosterol in the fungal cell membrane forming pores and increasing permeability. The altered permeability is toxic to the fungi leading to growth inhibition or death.
    SpectrumNystatin primarily targets the cell membrane of Candida species especially those which cause vaginal infections.
    Microbiology Applications

    Nystatin is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against fungal isolates. Medical microbiologists use AST results to recommend treatment options.  Representative effective ranges include:

      • Candida albicans 0.78 µg/mL - 400 µg/mL

    Plant Biology ApplicationsNystatin can be used in plant tissue culture to control contamination.
    Eukaryotic Cell Culture Applications

    Nystatin is commonly used to prevent contamination in cell culture. 

    Quantum dots can be used to deliver and monitor biomolecules, but the study of the uptake mechanism is just beginning.  Researchers found that Nystatin is a highly selective inhibitor of the lipid raft-dependent pathway and the uptake of SR9 is a lipid raft-dependent process, thus it can be a valuable compound for quantum dot research  (Xu et al, 2010).

     Nystatin can induce interleukin (IL)-1, IL-8, and tumor necrosis factor a secretion in TLR2-expressing THP1 cells.
