一般說明

N-月桂酰肌氨酸钠盐适用于需要严格控制元素含量的工艺。该产品有助于膜蛋白、糖蛋白的溶解和分离,以及 RNA 和质粒的分离。N-月桂酰肌氨酸钠盐用作消泡补充剂或细菌或其他细胞裂解缓冲液的成分。这表明胶束中间相的顺磁各向异性符号发生了变化。N-月桂酰肌氨酸钠盐对己糖激酶和人类唾液/肠道菌群的抑制率为 0.25%。它在水分散体(1%)中也表现出杀菌活性。N-月桂酰肌氨酸(LS)是一种具有蛋白质变性能力的阴离子表面活性剂,结构类似于月桂酸硫酸钠(SLS)。它在体外能使单纯疱疹病毒(HSV)失去传染性。它也可用作阴道外用制剂中的杀菌剂,以阻止HSV、人类免疫缺陷病毒1型(HIV-1)和其它导致性传播疾病(STD)的病原体的传播。

應用

N-月桂酰肌氨酸钠盐已被用作以下溶液的成分:
  • 核酸酶终止混合物,胚胎提取物缓冲液,用于解离染色质中非特异性结合的蛋白质
  • 蛋白酶 K 溶液,用于基因组 DNA 的热变性
  • 10%(w/v)肌氨酰/0.5M 乙二胺四乙酸(EDTA)溶液,用于制备 EDTA 肌氨酰蛋白酶(ESP)缓冲液
  • 杂交缓冲液,用于原位杂交组织化学
  • 胚胎提取缓冲液,用于解离染色质中非特异性结合的蛋白质
  • 蛋白酶K 溶液,用于使酶失活
