一般說明

三羟甲基氨基甲烷,常称为氨丁三醇、Tris 碱或Trizma碱,作为生物缓冲液在各种研究应用中发挥着至关重要的作用。由于8.1的最佳 pKa ,它被广泛用于Tris-乙酸盐-EDTA(TAE) 和Tris-硼酸盐-EDTA(TBE)等缓冲液配方,适用于将 pH 值维持在大多数生物体的生理范围内 (pH 7-9)。但是在研究一些蛋白质时务必谨慎,因为 Tris 碱可能会干扰某些酶的活性。Tris碱可单独用作缓冲液,也可用作混合缓冲液(包括Tris-EDTA (TE)缓冲液、TAE缓冲液和TBE缓冲液)配方的成分。重要的是,Tris碱的特征在于其纯度、稳定性和相对无吸湿性的性质。

在实验室环境中,Tris碱是制备与生物液相容的缓冲液必不可少的试剂,可作为标准pH 溶液。它有助于进行多种操作技术,如乳酸脱氢酶测试、原位杂交和细胞蛋白质提取。其多样化用途涵盖了细胞培养、生物化学和分子生物实验室应用,有助于细胞膜渗透性相关研究和缓冲液制备。

應用

三羟甲基氨基甲烷已用于:
  • 作为缓冲液用于乳酸脱氢酶测试、原位杂交技术和细胞蛋白质提取。[1][2][3]
  • 作为流式细胞术样品制备中的缓冲液用于拉曼光谱分析[4]
  • 作为蛋白印迹中的清洗缓冲液[5]
  • 作为组织脱细胞过程中的缓冲液成分 [6]

特點和優勢

  • 7-9 pH 范围内的高效缓冲能力,pKa为8.1 (25 °C)
  • 经测试证实重金属污染浓度低,从而确保其适用于各种应用
  • 可用于细胞生物学和生物化学研究

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.
