一般說明

十二烷基硫酸钠(SDS)也称月桂基硫酸钠,它是一种阴离子表面活性剂,广泛应用于各种科学应用,特别是分子生物学、生物化学和细胞生物学研究。它的功效来源于两性分子特性,这种特性使其可以同时与疏水和亲水分子相互作用。SDS是一种可以使蛋白质增溶和变性的多功能去污剂,这种特性使其成为蛋白质提取和纯化实验中的基本工具。在SDS-PAGE电泳中,通过破坏蛋白质结构,SDS有助于根据分子量进行蛋白质分离。

除了蛋白质分析以外,SDS的应用还包括脂质的电泳分离,从而使研究人员能够对这些重要的细胞成分进行研究和表征。此外,各种杂交和分子生物学技术中也用到了SDS,这体现了它在各种研究领域中的多功能性。SDS在离子和非离子条件下的功效进一步扩展了其用途,使其适用于各种实验环境和要求。它能够通过结合肽链并产生负电荷来裂解蛋白,从而有效消除了凝胶分离中蛋白质形状这一影响因素,确保了准确的蛋白质尺寸测定。

應用

十二烷基硫酸钠已用于:
  • 染色体免疫沉淀
  • SDS-聚丙烯酰胺凝胶电泳(SDS-PAGE)
  • 作为用于免疫印迹的放射免疫沉淀检测缓冲液的一种组分
用于增溶和蛋白质变性,适用于PAGE变性应用。 大多数蛋白质以1.4 g SDS/g 蛋白质的比例结合SDS。 相对于结合的SDS自带的总负电荷,蛋白质固有电荷几乎可忽略不计。 每种蛋白质的质荷比基本相同,且基于分子大小在凝胶中迁移。
阴离子洗涤剂

特點和優勢

  • 用于分子生物学和生物化学研究的多功能表面活性剂
  • 适用于电泳应用
  • 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。

分析報告

针对用于变性聚丙烯酰胺凝胶电泳进行了测试。
