Description générale

Chemical structure: tetracycline

Actions biochimiques/physiologiques

Mode of Action: Tetracycline passively diffuses through proin channels in the cell membrane, binding to 30S ribosomes and inhibits protein synthesis by preventing access of aminoacyl tRNA to the acceptor site on the mRNA-ribosome complex. It also binds to the bacterial 50S ribosomal subunit, altering the membrane and causing intracellular components to leak from bacterial cells. The inhibitory effects can be reversed by washing, suggesting that it is the reversibly bound antibiotic, and not the irreversibly bound drug, that is responsible for antibacterial action.

Mode of Resistance: The effects are inactivated via a loss of cell wall permeability.

Antimicrobial spectrum: Includes a wide range of antimicrobial activity against gram-positive and gram-negative bacteria.

Resistance to tetracycline emerged soon after its discovery six decades ago. Extensive clinical and non-clinical uses of this class of antibiotic over the years have combined to select for a large number of resistant determinants, collectively termed the tetracycline resistome.

Questions

1–3 sur 3 questions  

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

    1 réponse

    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

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

    1 réponse

    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/449/386/product-dating-information-mk.pdf

  3. How do I prepare a stock solution of T3258 Tetracycline? What is it soluble in?

    1 réponse

    1. This product is soluble in methanol or ethanol, giving a completely clear solution at up to 30 mg/ml. The stability of this material in solution is pH-dependent. Stock solutions prepared in ethanol are estimated to be stable for 1-3 months when aliquoted and stored at -20°C. Please see the link below to review the product datasheet which also lists the solubility in 1 M HCl. Note that the potency is reduced in solutions with a pH below 2. https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/406/734/t3258dat.pdf
