Application

Amphotericin B is used to study the affects of the influx of calcium on antifungal activity, and to study the binding and kinetics of Amphotericin B to sterols in monolayers, aqueous solutions, and phospholipid bilayers . It is also commonly used in tissue culture as an antifungal supplement.Amphotericin B from Streptomyces sp. has been used-for amphotericin perforated patch techniqueas a reference antifungal drug during MIC (minimum inhibitory concentration) agar dilution assayas a component of Arcobacter selective isolation broth

Biochem/physiol Actions

Amphotericin B binds to sterols, forming pores in the membrane, and causing small molecules to leak out. The product is most effective against fungi and yeast.

Caution

Amphotericin B remains active for 3 days in culture at 37°C. At -20°C, and with protection from air and light, the product remains active for 5 years.

General description

Chemical structure: polyene

Other Notes

Keep container tightly closed in a dry and well-ventilated place. Product is sensitive to light and moisture. Keep in a dry place.

Packaging

1, 5, 100 g in glass bottle

100, 250, 500 mg in glass bottle

Preparation Note

Amphotericin B is insoluble in water at pH 6 to 7, but soluble in water at pH 2 or 11. It is soluble in DMSO (30-40 mg/mL) and in dimethylformamide (2-4 mg/mL). Aqueous solutions cannot be sterile filtered due to poor solubility.
