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
- Buffers more than buffering agent: introducing a new class of stabilizers for the protein BSA.: Diese Studie unterstreicht die Verwendung von MOPS-Natriumsalz als neuartiges Stabilisierungsmittel für Rinderserumalbumin (BSA) und erweitert dessen Rolle über ein einfaches Puffermittel hinaus. Die Studie zeigt, wie MOPS-Natriumsalz die Stabilität der BSA unter verschiedenen Bedingungen verbessern kann, und bietet signifikante Erkenntnisse für biochemische Anwendungen und die Proteinkonservierung (Gupta BS et al., 2015).
Packaging
- Die aktuelle DRYPOUR®-Verpackungskonfiguration ist ein nestbares 50-Liter-Fass
- 25KG-DP stellt die Standard-Fertigverpackung dar
- Kleinere Mengen können für variable Konfigurationen in dasselbe Fass gefüllt werden
- Verbessert die Betriebseffizienz durch Verkürzung der Materialvorbereitungszeit und Erhöhung der Bedienersicherheit
- Minimiert das Anbacken hygroskopischer Salze
- Bietet dreifachen Schutz: vor Feuchtigkeit innen und außen sowie vor Verunreinigungen
- Dieses hochmoderne Verpackungssystem minimiert das Anbacken und verkürzt so den Zeitaufwand für die Materialaufbereitung erheblich
- PE-Fass mit unserem neuen Sicherheitsverschluss, einer Polyethylen-Innenhülle mit integrierten Trockenmittelbeuteln und einer atmungsaktiven Tyvek®-Innenhülle
- Die Trockenmittelbeutel sind fest in die Polyethylen-Innenhülle integriert
- Der dreifache Schutz bietet zwei unschätzbare Vorteile:
- Deutlich weniger Anbacken
- Keine Kontaminationsgefahr durch das Trockenmittel

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

Hi I was wondering if this compound MOPs free acid and the MOPS Sodium Salt have an expiry date?
1 answer-
These products are not assigned an expiration date. They is assigned a recommended retest date of 2 years after the quality release date. A recommended retest date is the period of time during which the products are expected to remain within established stability specifications, provided that they has been stored under defined conditions. After the Retest Date, samples should be examined to ensure that the products are still in compliance with the established specifications.
