Kit de ensayo Cell Meter™ de apoptosis de fosfatidilserina está diseñado para monitorear la apoptosis celular midiendo la translocación de fosfatidilserina (PS).
Descripción
Kit de ensayo Cell Meter™ de apoptosis de fosfatidilserina, Fluorescencia azul optimizada para lectores de microplacas
Los kits de ensayo Cell Meter™ son un conjunto de herramientas para monitorear la viabilidad celular. Existe una variedad de parámetros que se pueden utilizar para monitorear la viabilidad celular.
Este kit en particular está diseñado para monitorear la apoptosis celular midiendo la translocación de fosfatidilserina (PS). En la apoptosis, la PS se transfiere a la valva externa de la membrana plasmática. La aparición de fosfatidilserina en la superficie celular es un indicador universal de las etapas inicial/intermedia de la apoptosis celular y puede detectarse antes de que se puedan observar cambios morfológicos.
El kit está diseñado para monitorear la apoptosis celular midiendo la translocación de fosfatidilserina (PS), y utiliza nuestro sensor de PS Apopxin™ basado en moléculas pequeñas fluorescentes patentado que se une específicamente a PS con una afinidad mucho mayor que la anexina V (Kd < 10 nM). Tiene fluorescencia azul al unirse a la membrana PS. Se puede utilizar en formatos de microplaca, microscopio y citómetro de flujo, mientras que la mayoría de los demás kits de ensayo de apoptosis comerciales solo se utilizan con microscopio o plataforma de citometría de flujo.

Imagenes
Figura 1: Imagen de fluorescencia de células HeLa teñidas con el conjugado Apopxin™ Violet 450. Las células Jurkat se trataron sin (izquierda) o con estaurosporina 1 μM (derecha) a 37 ºC durante 4 horas. La intensidad de la fluorescencia se midió usando un microscopio con un juego de filtros violeta (excitación = 405 nm).
