Summary

Automatically generated

Dieses Protokoll präsentiert die Objektträgervorbereitung und das automatisierte Scoring des γ-H2AX-Foci-Assays an peripheren Blutlymphozyten. Um die Methode und Sensitivität des Assays zu veranschaulichen, wurden isolierte Lymphozyten in vitrobestrahlt. Diese automatisierte Methode des DNA-DSB-Nachweises ist nützlich für schnelle und biologische Dosimetrieanwendungen mit hohem Durchsatz.
