General description

Riboflavin belongs to the vitamin-B family and contains a pentose side chain ribitol.

Application

Riboflavin has been used:
  • to check the role of riboflavin diet in rats
  • as a supplement in HECM-6 medium (hamster embryo culture medium)[1]
  • as a supplement in the bacterial basal media[2]

Biochem/physiol Actions

Riboflavin is a key component of the redox cofactors flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) that are used by a wide variety of flavoprotein oxidoreductases, dehydrogenase(s), decarboxylase(s) and electron transporters. Riboflavin is involved in various cellular processes, including β oxidation in lipid metabolism, glucose metabolism, protection from cellular oxidative injury, DNA and RNA metabolism, gluconeogenesis, erythropoiesis and generation of corticosteroids. Riboflavin deficiency causes ariboflavinosis with symptoms such as sore throat, hyperemia, edema of oral and mucous membranes, cheilosis and glossitis.[3]

Questions

1–2 of 2 Questions  

  1. 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/418/501/product-dating-information-06-25-mk.pdf

  2. 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
