Amino Acid Sequence

Glp-Gln-Asp-Tyr(SO3H)-Thr-Gly-Trp-Met-Asp-Phe-NH2

Anwendung

Caerulein wurde verwendet, um bei Sprague-Dawley-Ratten, Mäusen und anderen Versuchstieren Pankreatitis zu induzieren.[1][2][3]

Biochem./physiol. Wirkung

Caerulein ist eine Substanz, die im Magen-Darm-Trakt regulatorisch ähnlich wie Cholecystokinin wirkt.[4] Es besitzt einen Tyrosinsulfat-Rest und induziert die Kontraktion der glatten Muskulatur. Die Aktivität ist ähnlich wie die von Gastrin.[5] Caerulein wird verwendet, um Zellsignale zu untersuchen, die durch NF-κB-bedingte Hochregulierung von Proteinen wie ICAM-1 (interzelluläres Adhäsionsmolekül-1) und entzündungsbedingte Proteine wie die NADPH-Oxidase und den Januskinase-Signalweg vermittelt werden.[6] Caerulein reguliert außerdem die Thermoregulation, Beruhigung und das Sättigungsgefühl.[5]
Die Wirkungen auf das Schmerzempfinden sind widersprüchlich. Es verhindert Gallenblasenschmerzen, Nierenkoliken und die Schmerzen beim intermittierenden Hinken; allgemein wird es jedoch als Antagonist der endogenen Opioide angesehen.

Questions

1–5 of 5 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.
