Визуализация взаимодействия белков ДНК по иммунофлюоресценции

Overview

This study explores the dynamics of DNA repair protein recruitment in human cells following DNA damage. By utilizing indirect immunofluorescence, the research investigates protein-protein interactions and the formation of repair protein foci at damage sites. HeLa cells are employed as a model system to analyze spatial and temporal patterns in protein localization.
