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.

一般說明
此外，它可维持细胞生理pH，保护细胞免受呼吸引起的二氧化碳波动的影响，保证细胞稳态。这项能力更胜碳酸氢盐缓冲液(NaHCO3)。除了这些适合细胞培养的优异特性，HEPES也适于各种生物学和生物化学研究。也可用于免疫沉淀、细胞裂解、活细胞成像等技术，提供稳定受控的实验环境。功能多样、pH缓冲能力出色、与其他分子的互作力低，HEPES是多个研究领域中不可或缺的工具。

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

Bonjour, Est-ce que ce produit H0887 peut-être congelé à -80°C sans risque de le faire précipiter ?
1 answer-
It is best not to freeze the product as received. However, should the product be inadvertently frozen, it is best to thaw the product slowly. Do not place the frozen product in an incubator or water bath. Once thawed, inspect for any precipitates before use. A clear, colorless solution will be suitable for further use. Should this buffer be required to prepare the stock solution of another reagent that requires freezer storage, thaw slowly if possible.
