Abstract
The combination of live cell imaging and laser micro-irradiation is an important technique to investigate the recruitment and kinetics of DNA repair molecules to DNA damage sites. In this chapter, we describe the detailed methods to study the dynamics of fluorescently tagged ATM protein kinase at laser-induced DNA double strand break (DSB) sites. The same protocol can be applied to analyze the recruitment and kinetics of other potential or known DNA repair proteins to DSB sites.
