Anwendung

Cholin, ein essenzieller wasserlöslicher Nährstoff, wird vom Körper zur Erzeugung von Phosphatidylcholin-Phosphatiden und Neurotransmittern wie Acetylcholin verwendet. Cholin wird für Untersuchungen eines breiten Spektrums biologischer Prozesse von der Stammzellenentwicklung bis zur Erforschung von neurologischen Krankheiten eingesetzt. Darüber hinaus ist ein alkalisches Zwischenprodukt für die Salzherstellung von Nutzen.

Biochem./physiol. Wirkung

Acylgruppenakzeptor

Substrate

Cholin-Acetyltransferase-Substrat

Sonstige Hinweise

Hinweis: Das Bicarbonate wird mit der alterungsbedingten Freisetzung von CO2 in Carbonat konvertiert.

Skin diseases such as lupus, cancer, psoriasis, and hyperhidrosis can potentially be treated effectively by suppressing allele-specific genes using small interfering RNA (siRNA). Injections of siRNA into skin, though effective, are painful and cover small surface areas and thus are

Mixing ionic liquids is a suitable strategy to tailor properties, e.g., to reduce melting points. The present study aims to widen the application range of low-toxic choline-based ionic liquids by studying eight binary phase diagrams of six different choline carboxylates.

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.
