Summary

Automatically generated

Este protocolo presenta la preparación de diapositivas y la puntuación automatizada del ensayo de focos γ-H2AX en linfocitos de sangre periférica. Para ilustrar el método y la sensibilidad del ensayo, se irradiaron linfocitos aislados in vitro. Este método automatizado de detección de ADN DSB es útil para aplicaciones de dosimetría biológica rápidas y de alto rendimiento.
