Figure 3From: XRCC1 and PCNA are loading platforms with distinct kinetic properties and different capacities to respond to multiple DNA lesionsMobility of XRCC1 and PCNA at DNA damage sites. (A) Two separate subnuclear spots of a transiently transfected Hela cell were microirradiated. The mobility of accumulated fluorescent fusion proteins was determined by bleaching one of the two spots 5 min after microirradiation and subsequent recovery measurements. Inset shows the bleached microirradiated site. Scale bar, 5 μm. (B) FRAP data from 11 individual experiments are shown as mean curves. Error bars represent the standard error of the mean.Back to article page
