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

General description
Application
- Preformulation Characterization, Stabilization, and Formulation Design for the Acrylodan-Labeled Glucose-Binding Protein SM4-AC.: This study focuses on the preformulation characterization, stabilization, and formulation of the acrylodan-labeled glucose-binding protein SM4-AC, highlighting the use of MES buffer in the process (Sahni et al., 2017).
- Evidences for Chlorogenic Acid--A Major Endogenous Polyphenol Involved in Regulation of Ripening and Senescence of Apple Fruit.: The research investigates the role of chlorogenic acid in the ripening and senescence of apple fruit, utilizing MES buffer in various biochemical assays (Xi et al., 2016).
- The interaction of nifedipine with selected cyclodextrins and the subsequent solubility-permeability trade-off.: This article examines the interactions between nifedipine and cyclodextrins, emphasizing the solubility-permeability trade-off and using MES buffer in experimental setups (Beig et al., 2013).
- Capillary electrophoresis microchips for separation and detection of organophosphate nerve agents.: This research uses MES buffer in capillary electrophoresis microchips for the separation and detection of organophosphate nerve agents (Wang et al., 2001).

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.
