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
- Fluorescent labeling of the root cap cells with the bioactive NBD-S chemical probe based on the cellulose biosynthesis inhibition herbicides: Diese innovative Studie demonstriert die Anwendung von HEPES in molekularbiologischer Qualität bei der Formulierung bioaktiver Sonden für die Fluoreszenzmarkierung von Wurzelhaubenzellen. Unter Verwendung von Herbiziden zur Hemmung der Zellulosebiosynthese als Modellsystem liefert diese Forschungsarbeit wertvolle Einblicke in die Pflanzenbiologie und hilft beim Verständnis der Zellwandstrukturen und -funktionen von Pflanzen. Die Verwendung von HEPES trägt dazu bei, den physiologischen pH-Wert während der Experimente aufrechtzuerhalten und gewährleistet die Stabilität und Wirksamkeit der verwendeten chemischen Sonden (Tamogami S et al., 2021).

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
