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
- 防腐剂：甲醛抑制微生物生长的能力令其成为生物学样品的有效防腐剂，防止腐败并确保分析用样品的完整性。这种特性的应用见于医学实验室、博物馆和防腐液。
- 固定剂：在历史上，甲醛可用作固定剂，可交联蛋白并保护显微镜检查用组织的结构。这种特性让研究人员能够以良好的清晰度观察解剖学细节和细胞成分。
- 变性剂：在分子生物学技术领域，如甲醛-琼脂糖凝胶电泳，甲醛使RNA分子变性，从而防止其形成二级结构，并实现基于尺寸的分离。这种技术对于基因表达和RNA完整性的研究有重要价值。

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
