General description
El dimetilsulfóxido (DMSO) es un disolvente aprótico. Las moléculas terapéuticas y tóxicas que no son solubles en agua suelen ser solubles en DMSO. El nitrógeno líquido utilizado junto con un crioprotector como el DMSO es un método muy utilizado para conservar las células. El DMSO se ha utilizado para preparar disoluciones madre de varias moléculas y también se utiliza como control para dichas moléculas. Se ha utilizado en el ensayo de migración celular para disolver las células después de la migración. El DMSO probada en BPC también cumple los requisitos de las aplicaciones biotecnológicas y de ingeniería tisular.
Application
El dimetilsulfóxido se ha utilizado como vehículo de control para cultivar e inducir la activación de células estrelladas hepáticas (HSC) in vivo.[1][1] También se ha utilizado para preparar una disolución de reserva para estudiar la citotoxicidad del ácido ferúlico (FA) en las células del núcleo pulposo (NP).[2]
Features and Benefits
