产品介绍 Product Description

General description

Chemical structure: polyene

Application

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.

Biochem/physiol Actions

两性霉素B可与甾醇结合，在膜中形成孔，并导致小分子的泄漏。该产品对真菌和酵母最有效。

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.

Other Notes

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

Disclaimer

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.
