    ● Product description:

    Amphotericin B is a polyene antifungal antibiotic from Streptomyces sp. It has a high affinity for sterols, primarily ergosterols, of fungal and bacterial cell membranes. After binding to sterols, it forms channels in the membranes, causing small molecules to leak out. Amphotericin B is effective against fungi and yeast. Normal usage for maintenance of cell cultures is 2.5 mg/l with penicillin and streptomycin in the medium. For cultures already contaminated with yeast and fungus, it is recommended to use this product at 2-4 times the normal level (5-10 mg/l), without penicillin and streptomycin for 2-3 subcultures. Once the infection is under control, normal maintenance levels of amphotericin B should be used. Amphotericin B is not soluble in H2O but in DMSO. Amphotericin B solubilized is a colloidal suspension of Amphotericin B, using sodium deoxycholate as the solubilizing agent. The product is approximately 45% amphotericin B, 35% sodium deoxycholate; the balance being sodium phosphate and sodium chloride.

    ● Preparation instructions:

    Amphotericin B solubilized is reconstituted at the water in a 2.5 mg/ml stock solution. The solution must be filtered to sterilize by 0.22μm membrane.

    ● Storage/Stability:

    The lyophylized powder amphotericin B solubilized can be stable for 5 years under -20℃ protected from air and light. Stock solutions at 2-8 °C are stable for up to 1 month.
