This technique facilitates the visualization of replisome antigen-tagged DNA adduct encounters and can be extended to the interactions of any protein with a DNA structure or lesion amenable to immunodetection. This method can be used to assess int

While replication fork collisions with DNA adducts can induce double strand breaks, less is known about the interaction between replisomes and blocking lesions. We have employed the proximity ligation assay to visualize these encounters and to characterize the consequences for replisome composition.
