Allgemeine Beschreibung

Chemical structure: phenicole

Anwendung

Chloramphenicol is a synthetic antibiotic, isolated from strains of Streptomyces venezuelae. It is often used for bacterial selection in molecular biology applications at 10-20 μg/mL and as a selection agent for transformed cells containing chloramphenicol reistance genes.

Biochem./physiol. Wirkung

Wirkungsweise: Chloramphenicol hemmt die bakterielle Proteinsynthese durch Blockierung des Peptidyltransferaseschrittes, indem es an die ribosomale 50S-Untereinheit bindet und die Bindung der Aminoacyl-tRNA an das Ribosom verhindert. Es hemmt auch die mitochondriale und chloroplastische Proteinsynthese und die ribosomale Bildung von (p)ppGpp, wodurch die rRNA-Transkription unterdrückt wird.

Resistenzmechanismus: Die Verwendung von Chloramphenicol-Acetyltransferase führt zur Acetylierung und Inaktivierung des Produkts.

Antimikrobielles Spektrum: Es handelt sich um ein Breitbandantibiotikum gegen grampositive und gramnegative Bakterien, das vor allem in der Augenheilkunde und in der Tiermedizin eingesetzt wird.

Angaben zur Herstellung

Stock solutions can be prepared directly in the vial at any recommended concentration. A solution at 50 mg/mL in ethanol yields a clear, very faint, yellow solution. Degradation of chloramphenicol in aqueous solution is catalyzed by general acids and bases. This rate of degradation is independent of the ionic strength and pH.

Sonstige Hinweise

Keep container tightly closed in a dry and well-ventilated place, Light sensitive. Storage class (TRGS 510): Non-combustible, acute toxic Cat.3 / toxic hazardous materials or hazardous materials causing chronic effects

Haftungsausschluss

Stock solutions should be stored at 2-8°C and are stable at 37°C for 5 days. Aqueous solutions are neutral and stable over a wide pH range, with 50% hydrolysis occurring after 290 days. Use of a borax buffered solution reduces this number to 14%. Solutions should be protected from light as photochemical decomposition results in a yellowing of the solution. Heating aqueous solutions at 115°C for 30 minutes results in a 10% loss of chloramphenicol.

Terbinafine resistance is increasingly reported in Trichophyton, rendering susceptibility testing particularly important in non-responding cases. We performed a multicentre evaluation of six EUCAST-based methods. Ten laboratories susceptibility tested terbinafine, itraconazole, voriconazole and amorolfine against a blinded panel of 38 terbinafine

Proliferating cells require coordinated gene expression between the nucleus and mitochondria in order to divide, ensuring sufficient organelle number in daughter cells [1]. However, the machinery and mechanisms whereby proliferating cells monitor mitochondria and coordinate organelle biosynthesis remain poorly understood.

Questions

1–2 of 2 Questions  
  1. 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

  2. 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
