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.

一般描述
在核酸纯化中，硫氰酸胍可有效灭活DNA酶和RNA酶，从而防止核酸降解，保证可观产量。这种蛋白变性和酶抑制的双重特性令其成为DNA和RNA研究的重要工具。除了核酸分离，硫氰酸胍还能在RNA和DNA提取实验中用于裂解细胞和灭活病毒颗粒。它不仅能破坏各种膜，还能使RNA酶和DNA酶变性，保护提取的核酸免遭酶降解。功能丰富的硫氰酸胍适合各种分子生物学技术，包括PCR、Northern blotting和Southern blotting。在这些实验中作为重要试剂发挥作用，成功实现核酸的分析和扩增。

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
