Amphotericin B is a polyene antifungal antibiotic from Streptomyce sp. It has a high affinity for sterols, especially ergosterols, of both fungal and bacterial cell membranes. Normal usage in maintenance of antifungal cell cultures is 2.5 mg/L with penicillin and streptomycin used in the medium.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Ações bioquímicas/fisiológicas

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

Antimicrobial Spectrum: The product is most effective against fungi and yeast.


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.

Nota de preparo

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.

Recently, the structure-function relationships between amphotericin B (AmB) and ergosterol have been solved using synthetic techniques that require a mycosamine-mediated direct binding interaction between AmB and ergosterol to form AmB ion channels. However, studies to directly probe the AmB-induced membrane
