Application

N-(3-Oxododecanoyl)-L-homoserine lactone (3-Oxo-C12-HSL), a member of a family of acyl homoserine lactones, may be used to determine its mechanisms and specificity of action as a signaling molecule involved in the regulation of bacterial quorum sensing.[1][2]

Biochem/physiol Actions

N-(3-oxododecanoyl)homoserine-L-lactone (3-oxo-C12-HSL) is among a group of homoserine lactones that includes: N-octanoyl-homoserine lactone (N-C8-HSL), N-(3-oxodecanoyl) homoserine-L-lactone (3-oxo-C10 HSL), N-(3-Oxotetradecanoyl)-L-homoserine lactone (3-oxo-C14-HSL, N-(3-hydroxydecanoyl)-L-homoserine lactone, and N-(3-hydroxyoctanoyl)-L-homoserine lactone involved in the processes of bacterial quorum sensing. These N-acyl-homoserine lactones are used to study the processes and mechanisms of bacterial quorum sensing.
Acyl homoserine lactone that is an autoinducer of quorum sensing by Pseudomonas aeruginosa. Degraded by paraoxonase (PON) family members.

Questions

1–2 of 2 Questions  
  1. 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

  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.
