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.

General description
Application
- A crosslinker in the synthesis of hydrogel microparticles with a porous hydrogel structure. This porosity is essential for enhancing biomolecule accessibility and mass transport, which are critical for the performance of biosensing applications.
- A cross-linking agent in the preparation of molecularly imprinted polymers, that can selectively bind to oxidized low-density lipoprotein (oxLDL). The cross-linking enhances the mechanical stability and structural integrity of the polymer matrix.
- A cross-linking agent in the preparation of hydrogels or polymer matrices that support biological imaging applications.

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

How can I make 2% dheba for my expansion microscopy protocol? It seems that it doesn’t dissolve easily in water.
1 answer-
This product is not tested for solubility.
A literature search yielded the following: "Cross-linking agent for polyacrylamide gel electrophoresis that produces a gel which is soluble in dilute periodic acid or dilute aqueous solutions of bases". This information is from 'Polyacrylamide gels with modified cross-linkages' (P B O'Connell and C J Brady, Analytical biochemistry, 76(l), undefined (1976-11-1))
There is also a recommendation to incubate at 50 °C for 16 hours until solubilized (in Periodic acid).

Where do you store the powder form of DHEBA? Does it need to be desiccated after opening?
1 answer-
Storage conditions are at ambient temperatures in accordance with section 7 of the Safety Data Sheet.
