Opis ogólny

Ethylenediaminetetraacetic acid (EDTA) is a polyprotic acid and a metal chelating agent. It comprises four carboxylic acid and two amine groups with lone-pair electrons that can chelate calcium and several other metal ions. 

Zastosowanie

Ethylenediaminetetraacetic acid tetrasodium salt dihydrate has been used:
  • in the decalcification of femurs for the histoprocessing and staining of osteochondral tissue
  • as a component of NH4Cl lysis buffer for erythrocyte lysis and bulk characterization
  • for the isolation of crypts from the connective tissues of mice

Działania biochem./fizjol.

Ethylenediaminetetraacetic acid (EDTA) is used to eliminate enzyme inhibition by traces of heavy metals, and to inhibit enzymes that require divalent cations as cofactors.
Ethylenediaminetetraacetic acid (EDTA) is used to treat patients poisoned with heavy metal ions. It functions as a chelator of the zinc ion in the active site of metalloproteases. EDTA inhibits other metal ion-dependent proteases such as calcium-dependent cysteine proteases. It might interfere with biological events which are metal ion-dependent. EDTA inhibits platelet aggregation and is the most preferred anticoagulant for platelet counts. It associates with other active agents to modulate microorganisms and biofilms, like citric acid, alcohol, antibiotics, polyhexamethylene biguanide (PHMB) quaternary ammonium compounds, and other antiseptics. EDTA is used as an anticoagulant for hematological testing, as it preserves the cellular components and morphology of blood cells.

Leukocyte isolation from whole blood to study inflammation requires the removal of contaminating erythrocytes. Leukocytes, however, are sensitive to prolonged exposure to hyper/hypoosmotic solutions, temperature changes, mechanical manipulation, and gradient centrifugation. Even though care is taken to minimize leukocyte activation

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.
      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
