Abstract

En la presente se describen medios para la detección y caracterización de neurotoxinas como la neurotoxina botulínica (BoNT) o neurotoxina tetánica La presente descripción proporciona métodos para determinar la potencia y actividad de las neurotoxinas in vitro e in vivo. También se describen polipéptidos que comprenden fragmentos de extremo N y C de una proteína indicadora que se dividen mediante un enlazador que comprende un sitio de escisión de neurotoxina. La escisión del enlazador por una neurotoxina disminuye la actividad de la proteína indicadora, lo que indica la actividad de la neurotoxina. También se describen las composiciones y kits que comprenden los polipéptidos descritos, los ácidos nucleicos que comprenden secuencias de nucleótidos que codifican dichos polipéptidos y las células que expresan dichos polipéptidos.
