Application

Ethylenediaminetetraacetic acid has been used:
  • as a component of peptide dilution buffer for intracellular BH3 (Bcl-2 homology (BH) domain) profiling and validation[1]
  • as a medium component in the hepatic stellate cell (HSCs) culture[2]
  • as a component of homogenization buffer for protein extraction from eye tissues[3]
  • for stopping benzonase reaction in lysis buffer[4]

Biochem/physiol Actions

Ethylenediaminetetraacetic acid (EDTA) is an anticoagulant, majorly used in preventing clotting of blood samples.[5] EDTA may trigger aggregation of platelets resulting in pseudothrombocytopenia.[6] EDTA along with tetracycline imparts serves as root conditioning agent and provides relief in gum infection.[5] EDTA-tetracycline therapy decreases coronary artery calcium levels in atherosclerosis.[7] Calcium Disodium EDTA administration is effective in slowing down the progression of chronic kidney disease.[8]

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.

  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
