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, [1] and to study the binding and kinetics of Amphotericin B to sterols in monolayers, aqueous solutions, and phospholipid bilayers [2][3]. 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[4]
  • as a reference antifungal drug during MIC (minimum inhibitory concentration) agar dilution assay[5]
  • as a component of Arcobacter selective isolation broth[6]

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

Tightly closed. Dry. Keep in a well -ventilated place. Keep locked up or in an area accessible
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.

Questions

1–3 of 3 Questions  
  1. I would like to perform a MIC assay and any powder that is not completely dissolved may affect the accuracy and reproducibility of MIC results. May I know if this product can fully dissolved in DMSO?

    1 answer
    1. The solubility in DMSO is listed as 30-40 mg/mL. It may be soluble above that concentration, but it would need to be tested empirically by the end user.

      Helpful?

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  3. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
