一般描述

抗坏血酸钠,又称矿物质抗坏血酸,是抗坏血酸的钠盐,通常称为维生素C。这种水溶性分子有多种用途,尤其是在细胞生物学中,是一种重要的还原剂,可减轻氧化应激。从生化研究方面看,它是人类和动物的重要营养素。此外,抗坏血酸钠作为细胞代谢中多种酶的辅因子,在代谢组学研究中起着内源性抗氧化剂、辅酶和代谢物的作用。

在生化研究中,L-抗坏血酸钠盐表现出其作为胶原蛋白沉积增强剂和弹性蛋白生成抑制剂的多功能性。这些属性有助于它广泛应用于理解细胞过程和机制,使其成为探索生物化学、代谢组学和细胞生物学各个方面的不可或缺的工具。
维生素C(抗坏血酸)是一种低分子量碳水化合物,它具有一个烯-二醇结构。它是在自然界中丰富存在的水溶性电子供体。水果蔬菜中富含维生素C。

应用

(+)-抗坏血酸钠 L被用于:
  • 研究芦荟食品补充剂抗氧化和细胞毒理学作用的标准品
  • 使用5-乙炔基-2′-脱氧尿苷(EdU)检验线粒体DNA复制时溶液B的制备
  • 制备EdU-标记溶液
  • 制备 β-半乳糖苷酶染色液

生化/生理作用

维生素C(抗坏血酸)作为还原剂。它在血管功能中发挥重要作用。

特点和优势

  • 可用于代谢组学和生物化学研究
  • 适用于多种研究应用的优质化合物

Adenoviruses (AdVs) cause respiratory, ocular, and gastrointestinal tract infection and inflammation in immunocompetent people and life-threatening disease upon immunosuppression. AdV vectors are widely used in gene therapy and vaccination. Incoming particles attach to nuclear pore complexes (NPCs) of post-mitotic cells, then rupture

Antioxidants protect biological systems from oxidative damage produced by oxygen-containing free radicals and from redoxactive transition metal ions such as iron, copper, and cadmium.

抗氧化剂可保护生物系统免受含氧自由基和氧化还原过渡金属离子(如铁、铜和镉)引起的氧化损伤。

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
