一般說明

醋酸钾(KAc)是强碱弱酸醋酸盐。它可用作缓冲剂,使酶反应和蛋白质研究维持最优的pH水平。KAc兼容生物体系,因而成为生物分子分离、纯化和分析的首选。在生物测定体系中,它还可稳定酶并维持最优条件,因而在生化研究中不可或缺。此外,KAc 是色谱和电泳技术的不二之选,有助于生物分子的分离和分析。

應用


  • Study on the Freeze-Thaw Resistance of Concrete Pavements in Seasonally Frozen Regions.: This study investigates the freeze-thaw resistance of concrete pavements in areas that experience seasonal freezing, emphasizing the role of chemical additives like potassium acetate in enhancing durability (Zhao et al., 2024).

  • Harmonising IV Oxycodone with Paediatric Perioperative Medications: A Compatibility Study Through Y-Type Connectors.: This research explores the compatibility of IV oxycodone with various paediatric perioperative medications, including potassium acetate, to ensure safe administration (Youssef et al., 2024).

  • Gene Expression of Ethanol and Acetate Metabolic Pathways in the Acinetobacter baumannii EmaSR Regulon.: This research examines the metabolic pathways of ethanol and acetate in Acinetobacter baumannii, highlighting the regulatory role of potassium acetate in gene expression (Huang et al., 2024).

生化/生理作用

醋酸钾 (KAc) 缓冲液有助于从植物和蜱虫等各类样品中提取 DNA。利用这一成分可获得可供测试更多标志物的DNA,针对同一样品测试多种标志物时强烈建议选用。在色谱和电泳技术应用中,KAc 可作为生物分子分离和分析的有效缓冲体系。此外,它还可用作活化剂,用茶叶渣制备活性炭吸附酸性蓝25(AB25)染料。
