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.

Application
- MIL-101(Fe) based biomass as permeable reactive barrier applied to EK-PRB remediation of antimony contaminated soil.: The research utilizes EDTA as a chelating agent to enhance the performance of a MIL-101(Fe) based reactive barrier for the electrokinetic remediation of antimony-contaminated soil (Wang et al., 2023).
- Proteomic signatures of synergistic interactions in antimicrobials.: This proteomics study investigates the synergistic interactions of antimicrobials, highlighting the role of EDTA in enhancing antimicrobial efficacy by disrupting microbial cell membranes (Zhou et al., 2023).
- Rapid and zero-cost DNA extraction from soft-bodied insects for routine PCR-based applications.: This study presents a novel method for DNA extraction using EDTA, which simplifies and reduces the cost of DNA extraction from soft-bodied insects for PCR applications (Jangra and Ghosh, 2022).

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