Popis

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

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.

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

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.
