Descripción general

El dodecilsulfato sódico (SDS) es un tensioactivo aniónico. También se denomina lauril sulfato.

Aplicación

El dodecilsulfato sódico (SDS) se ha utilizado:
  • en la caracterización de la cepa de enterobacterias basada en la sensibilidad a compuestos selectivos
  • para tratar la piel humana in vitro ein vivo para evaluar el papel de la localización nuclear de la proteína de choque térmico de 27 kDa (HSP27) en la posible irritación cutánea
  • en la descelularización del tejido de las válvulas cardiacas porcinas
  • para el tratamiento de los espermatozoides destinado a la inducción in vitro de la descondensación de la cromatina de los espermatozoides

Detergente aniónico.

Acciones bioquímicas o fisiológicas

El dodecilsulfato sódico (SDS) contribuye a alterar rápidamente las membranas biológicas. Suele utilizarse como uno de los principales componentes de diversos reactivos que se utilizan para purificar los ácidos nucleicos. El SDS puede bloquear la actividad de la ARNasa y la desoxirribonucleasa (ADNasa).
