Research Antibiotics, Amphotericin B, Solubilized, 250 mg

Amphotericin B, Solubilized, 250 mg. This is a solubilized form of Amphotericin B, a polyene antibiotic used to control contamination from fungi, viruses, and protozoa. Amphotericin B is derived from Streptomyces nodosus and is nearly insoluble in water in its standard form. The addition of sodium deoxycholate is required in order to maximize the solubility.

We offer 3 forms of Amphotericin B:

• Amphotericin B, EP (TOK-A064)
• Amphotericin B, USP (TOK-A007)
• Amphotericin B, solubilized (TOK-A008)

Description

• Family: Microbiology
• CAS Number: 1397-89-3
• Molecular Formula: C₄₇H₇₃NO₁₇
• Molecular Weight: 924.08
• Mechanism of Action: Amphotericin B associates with membrane sterols (ergosterol in fungal cell membranes, and cholesterol in mammalian cell membranes). Amphotericin B forms a pore in these membranes resulting in leakage of essential ions and ultimately cell death.
• Storage Conditions: 2-8°C
• Tariff Code: 2941.20.5000
• Spectrum: Amphotericin B is active against mammalian cells, fungi, viruses, and protozoa. Amphotericin B is not toxic to bacteria due to their lack of sterols. The following represents MIC susceptibility data for amphotericin B against common fungal pathogens:
  • Candida albicans - 0.001 - 321 µg/mL
  • Candida krusei - 0.001 - 16 µg/mL
  • Coccidioides immitis - 0.0625 - 2 µg/mL
  • Cryptococcus neoformans - 0.2 - 39 µg/mL
  • Fusarium oxysporum - 0.75 - 125 µg/mL

Specifications

• Form: Powder
• Appearance: Yellow or Orange powder
• Source: Streptomyces nodosus
• Assay (As Is): ≥240 µg/mg
• Impurities
  Mycoplasma: None detected
• Endotoxin: ≤40 EU/mg

Eukaryotic Cell Culture Applications

Amphotericin B can be used in eukaryotic cell culture to control or prevent contamination from fungi, viruses, and protozoa. Amphotericin B can be toxic to cell lines at high concentrations and should not be used at concentrations greater than 2.50 µg/mL. Amphotericin B has been used in vitro to inhibit the generation of the scrapie isoform of the prion protein when studying transmissible spongiform encephalopathies (Mangé et al 2000).

Microbiology Applications

Amphotericin B is used as an antimycotic selective agent in several routinely used selective media formulations to inhibit the growth of background fungal growth. It can also combat viruses and protozoa.

Plant Biology Applications

Amphotericin B can be used to inhibit phytopathogenic fungi in vitro
