Application

25-Hydroxycholesterol was used to treat mouse neuroblastoma cells to activate the ABCA1 signaling[1] and in studies related to fatty acid metabolism.[2][3]

Biochem/physiol Actions

25-Hydroxycholesterol is a side-chain oxysterol that reportedly triggers activation of a number of cholesterol molecules. This triggers their movement from cell membrane to the endoplasmic reticulum (ER).[4] 25-Hydroxycholesterol affects the immune system and has a key role in the pathogenesis of atherosclerosis.[5]
Suppresses the cleavage of sterol regulatory element binding proteins (SREBPs). 25-Hydroxycholesterol induces apoptosis through down-regulation of Bcl-2 expression and activation of caspases.

Preparation Note

A stock solution of 25-Hydroxycholesterol may be prepared in ethanol and dissolved in cell culture medium to give a final concentration of 1 mg/ml.

Side-chain oxysterols are enzymatically generated oxidation products of cholesterol that serve a central role in mediating cholesterol homeostasis. Recent work has shown that side-chain oxysterols, such as 25-hydroxycholesterol (25-HC), alter membrane structure in very different ways from cholesterol, suggesting a

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.
      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
