General description

Aspartic acid is a non-essential amino acid.[1] L-Aspartic acid is a dicarboxylic amino acid, which is involved in the synthesis of nerve cells proteins. It also stimulates the depolarization of nerve cell membranes.[2] L-Aspartic acid acts as an amine donor for transamination reaction.[3]

Application

L-Aspartic acid sodium salt monohydrate has been as a component of reservoir solution for crystallization.[4][5]

Biochem/physiol Actions

Hauptneurotransmitter für schnelle synaptische Anregung
Selective outflow of L-aspartic acid across the blood-brain barrier controls the level of L and D aspartic acid in the brain. Increased levels of L-aspartic acid in the brain results in excitatory neurotoxicity.[6] Recent studies highlight that racemization of L-aspartic acid is followed by the determination of D:L ratio to estimate the age of an individual.[7]

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
