一般說明

氧化砷（ATO）是一种无机形式的砷，可用作治疗急性早幼粒细胞白血病（APL）患者的治疗化合物。目前正在开发许多药物传递方法，利用纳米技术克服由于快速从血液中清除而导致生物利用度差的问题。[1][2][3]

應用


  • 电化学检测应用：一项关于包含功能化碳纳米纤维的镧基钙钛矿的研究强调了三氧化二砷在水和食品样品中洛克沙砷（roxarsone）电化学检测的用途，提供了一种提高安全性和环境监测方法 (John Felix MA et al., 2024）。

  • 癌症研究中的抗增殖作用：该研究显示了三氧化二砷与二甲双胍联用对KG1a细胞增殖的抑制作用，表明其在抗肿瘤策略制定方面的潜在效用(Huang-Li WH et al., 2024）。

  • 环境修复：这篇关于氧化锰基除砷材料的综述讨论了三氧化二砷在环境修复中的应用，重点介绍了砷净化技术的有效性和进展 （Younas M et al., 2024）。

Questions

1–2 of 2 Questions  

  1. 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

  2. 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
