应用

碘化钾已用于：
  • 抑制活性氧作为 DNA 损伤等过程的组分[1]
  • 作为一种混沌剂，在高浓度下溶解凝胶基质[1]
  • 通过凝胶溶解从凝胶片中回收 DNA[1]

生化/生理作用

碘化钾（KI）由卤素碘和碱金属钾组成。它以加碘盐的形式用于治疗地方性甲状腺肿。KI 也用于治疗甲状腺功能亢进和甲状腺辐射防护。KI 常用于Grave病患者的术前准备。它也可用于治疗皮肤病，如皮肤孢子虫病和各种炎症性皮肤病。碘化钾常被用作祛痰药。它在体外抑制中性粒细胞产生有毒氧中间体过氧化氢和羟基自由基的能力。

Questions

1–2 of 2 Questions  

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

    1 answer

    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. 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
