General description

十二烷基硫酸钠（SDS）是一种众所周知的阴离子去污剂，在科学研究中广泛用于蛋白质二级和三级结构的变性。它包含一条12个碳原子的非极性链，末端为带负电的硫酸基团。SDS有助于蛋白质的变性和增溶，它是聚丙烯酰胺凝胶电泳等过程的基本试剂，在凝胶电泳中有助于测定蛋白质分子量。此外，SDS可作为一种有机钠盐，并可充当去污剂和蛋白质变性剂的双重角色。它的独特性质在于阴离子表面活性剂的性质，特征在于带负电荷。这种电荷促进了与蛋白质和脂质的相互作用，从而导致胶束结构的形成。这些胶束是SDS能够有效溶解和稳定蛋白质和脂质的关键，便于研究人员在科学研究中对其进行详细研究和处理。SDS的两亲特性来源于一条带负电硫酸根的长链脂肪基团，这种性质使其成为各种生物分子实验和研究中的重要去污剂。

Manufacturers of latex immunoassays have typically added surfactants to improve detection sensitivity and prevent non-specific aggregation of microspheres, which may cause both false positives and negatives during diagnostic testing. There is also growing interest in conducting immunoassays in smaller volumes
