Abstract

La presente invención se refiere a un método biológico para someter a ensayo los peptidoglicanos (PGN) en una muestra, en particular una muestra de polímeros de glucosa. El ensayo de PGN incluye: a) tratar la muestra de polímeros de glucosa mediante sonicación, calentamiento y/o alcalinización; b) poner en contacto la muestra tratada o una dilución de esta con una célula recombinante que exprese un TLR2 exógeno (receptor de tipo Toll 2) y un gen indicador que dependa directamente de la ruta de señalización asociada con el TLR2. El gen indicador codifica una proteína coloreada o fluorescente o una proteína cuya actividad es medible con o sin un sustrato; c) medir la señal del gen indicador; y d) determinar la cantidad de PGN en la muestra utilizando una curva patrón de la correlación entre la cantidad de PGN y la intensidad de la señal del gen indicador.
