- 14:57Conclusion
La hibridación fluorescente in situ (FISH) permite la detección de ácidos nucleicos en su ambiente nativo dentro de las células. Se describen un protocolo para el combinado, la detección simultánea de ARN y ADN por medio de pescado, que se puede utilizar para estudiar inactivación del cromosoma X en las células madre embrionarias de ratón.
