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
Die Vielseitigkeit von EDC-HCl zeigt sich weiter in der Fähigkeit zur Modifizierung von Nukleinsäuren, die die Markierung von DNA und RNA über ihre 5′-Phosphatgruppen ermöglicht. Diese Funktion verbessert die Visualisierung, Nachverfolgung und Analyse dieser wichtigen Moleküle und trägt signifikant zum Fortschritt in der Nukleinsäureforschung bei. Darüber hinaus dient EDC-HCl als Brücke für wichtige Biomoleküle, indem es als Crosslinker fungiert, der aminreaktive NHS-Ester aus Biomolekülen mit Carboxylgruppen verbindet. Diese Technik erweist sich als besonders wertvoll bei der Proteinkonjugation und ermöglicht die Erzeugung von Hybridmolekülen mit neuartigen Eigenschaften und Funktionen. Der zugrunde liegende Mechanismus von EDC-HCl umfasst die Reaktion mit einer Carboxylgruppe, die ein instabiles Zwischenprodukt bildet, das aktiv einen Aminpartner sucht. Das empfindliche Gleichgewicht dieser Reaktion unterstreicht die Notwendigkeit der Optimierung von Bedingungen, um eine effiziente Konjugation zu gewährleisten. Durch die Unterstützung von N-Hydroxysuccinimid (NHS) werden die Fähigkeiten von EDC-HCl weiter verbessert, das Zwischenprodukt stabilisiert und Konjugationsverfahren in zwei Schritten ermöglicht. Dies bietet mehr Flexibilität und Kontrolle, insbesondere bei komplexen Biomolekülen.
Application

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

Can N-(3-Dimethylaminopropyl)-N´-ethylcarbodiimide hydrochloride, Product E7750, be used as a peptide coupling reagent in alcoholic solvents? If so, do you have a reference?
1 answer-
Yes. Nosaki, S., Effects of amounts of additives on peptide coupling mediated by a water-soluble carbodiimide in alcohols. J. Peptide Res., 54(2), 162-167 (1999). This paper describes using the E7750 along with 3,4-dihydro-3-hydroxy-4-oxo-1,2,3-benzotriazine (HOOBt) and 1-hydroxy-7-azabenzotriazole (HOAt) for enhancement of peptide coupling.
