Allgemeine Beschreibung

Riboflavin is an essential vitamin soluble in water. Milk and eggs are found to be its major sources. Riboflavin is usually bound to enzymes in all tissues. During riboflavin localization in plasma, it is bound to albumin and specific immunoglobulins.[1]

Anwendung

(-)-Riboflavin has been used to study its antimicrobial effect in vitro,[2] through ultraviolet light A (UVA) activation.[3][4]It has also been used collagen coated surface of the polyethylene membrane for cross-linking astrocytes.[5]

Biochem./physiol. Wirkung

Riboflavin serves as a precursor for the active enzyme cofactors riboflavin 5′-monophosphate (also called flavin mononucleotide or FMN) and flavin adenine dinucleotide (FAD).[1] Riboflavin deficiency in the diet results in a well-defined syndrome known as ariboflavinosis,[6] Riboflavin exhibits protective effects against tumor development and cardiovascular disease. Its deficiency often affects metabolism involving redox reactions. Riboflavin is found essential for iron absorption, gastrointestinal development, neurogenesis, corneal vascularization and corneal opacity.[1]

Fragen

1-2 von 2 Fragen  

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

    1 Antwort

    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 Antwort

    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
