Description

Biochem/physiol Actions

Mode of Action: Nystatin acts by binding to ergosterols in fungal cell membranes, increasing permeability of the membrane, and creating nystatin/ergosterol based ion channels. It also functions as a lipid raft-inhibiting reagent and as membrane associated cholesterol.

Antimicrobial spectrum: Neomycin acts against fungi, yeasts and molds.

Caution

Nystatin in tissue culture media is stable at 37°C for three days. It is also stable in moderately alkaline media. Solutions and aqueous suspensions begin to lose activity soon after preparation, with heat, light, and oxygen accelerating the decomposition. Aqueous suspensions are stable for 10 minutes when heating to 100°C at pH 7.

Packaging

5000000, 25000000 units in poly bottle

Preparation Note

Nystatin is soluble at 28°C in methanol (11.2 mg/mL), ethanol (1.2 mg/mL), carbon tetrachloride (1.23 mg/mL), chloroform (0.48 mg/mL), benzene (0.28 mg/mL), and ethylene glycol (8.75 mg/mL). It is also soluble in DMSO at 5 mg/mL and freely soluble in DMF and formamide. It is not recommended to autoclave or sterile filter solutions of Nystatin. Prepare 50 mg/mL stock suspensions in water and store at -20°C.

Application

Nystatin is a polyene antibiotic. Its uses include preventing cell culture contamination and inducing interleukin (IL)-1, IL-8, and tumor necrosis factor α secretion in TLR2-expressing THP1 cells†. This product is recommended for use in cell culture applications at 50 mg/L.
