Application

十二烷基硫酸钠(SDS)已用于:
  • 带负电荷的表面活性剂,研究其在表面活性剂稳定乳液的微滤期间对过滤通量和膜污染的影响
  • 植物提取缓冲液和传递缓冲液的组分用于蛋白质印迹
  • 5× Laemmli样品缓冲液(5× LB)和10×SDS运行缓冲液的组分,以进行十二烷基硫酸钠聚丙烯酰胺凝胶电泳(SDS-PAGE)和免疫印迹

阴离子洗涤剂

Biochem/physiol Actions

十二烷基硫酸钠(SDS)通过硫酸基团和烷基链有效地与蛋白质的正电荷和疏水残基结合。在结构生物学和蛋白质折叠/去折叠研究中,它是一种重要的清洁剂。SDS可刺激蛋白质结果中α-螺旋链的产生。它具有促进多种蛋白质,包括牛血清蛋白(BSA)、β-乳球蛋白、α-乳清蛋白和蛋清溶菌酶等,在高浓度下的协同去折叠能力。 

Features and Benefits

  • 经测试确认重金属污染水平较低,确保适用于各种应用
  • 检测痕量阴离子和阳离子
  • 生化研究的高纯度产品

General description

十二烷基硫酸钠(SDS)是一种有机钠盐,在生物化学研究中用作洗涤剂和蛋白质变性剂。其独特的结构包括长链脂肪基团和带负电荷的硫酸盐,使其成为使蛋白质变性的有效试剂。这种特性在电泳中特别有价值,电泳是一种用于分离和分析蛋白质等大分子的技术。SDS带负电荷,与蛋白质和脂质相互作用,形成胶束结构,有助于溶解和稳定这些生物分子。
