General description
細胞培養に幅広く使用されているHEPESは、安定した生理的pHを維持することに優れており、これは細胞呼吸によって二酸化炭素濃度の変動が生じても変わりませんが、重炭酸塩バッファーにおいてはそれほど機能しません。また、等電点電気泳動法においては、pH勾配を形成するための両性分離剤として機能します。さらに、DNA制限酵素反応に対しては、置換アミン基の数が少ないトリスなどのバッファーよりも低いレベルの干渉を示します。これらの用途以外にも、HEPESは免疫沈降、細胞溶解、および生細胞イメージングを含むさまざまな生物学的および生化学的研究に使用できる可能性があります。この優れた汎用性から、さまざまな研究用途に不可欠なツールとなっています。

How can I determine the shelf life / expiration / retest date of this product?
1 回答-
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.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 回答-
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
