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.

Analysis Note
Teneur en sulfates : sert d'indicateur de pureté, le sulfate étant le principal groupement ionique présent.
Force du gel : équivaut à la force qu'il faut appliquer sur le gel pour le rompre.
Point de gélification : correspond à la température à laquelle une solution aqueuse d'agarose forme un gel en refroidissant. Les solutions d'agarose présentent une hystérésis lorsqu'elles passent de la forme liquide à la forme gélifiée, ce qui signifie que leur point de gélification n'est pas égal à leur température de fusion.
Électro-endosmose (EEO) : définit un mouvement de liquide à travers le gel. Les groupements anioniques d'un gel d'agarose sont fixés à la matrice et ne peuvent pas bouger, mais les contre-ions positifs dissociables peuvent migrer dans la matrice en direction de la cathode, créant ainsi une EEO. Comme le déplacement électrophorétique des biopolymères se fait généralement vers l'anode, l'EEO peut perturber les séparations en raison d'une convection interne.

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
