Description

General description

Amphotericin B is a polyene antifungal antibiotic from Streptomyces sp. and has a high affinity for sterols, especially ergosterols, of both fungal and bacterial cell membranes.

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 technique
• as a reference antifungal drug during MIC (minimum inhibitory concentration) agar dilution assay
• as a component of Arcobacter selective isolation broth

Biochem/physiol Actions

Mode of Action: Amphotericin B binds to sterols, forming pores in the membrane, and causing small molecules to leak out.

Antimicrobial spectrum: Includes fungi and yeast

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.

Features and Benefits

High quality antibiotic suitable for mulitple research applications

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.

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.

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.
