Summary

Automatically generated

Il metodo qui presentato descrive un saggio per seguire l'attivazione di specifici RhoA PIL / GTP Fattori di cambio (GEFs) in cellule coltivate facendo uso di una proteina di fusione GST RhoA mutante che ha un'elevata affinità per GEFs attivati. GEFs vengono precipitati da lisati cellulari, rilevati da Western blotting e quantificato mediante densitometria.
