Figure Lengend Snippet: Prolonged accumulation of pre- and post-incision factors at NER sites in the presence of replication inhibitors. (A) Fluorescent immunostaining of XPB, RPA, Polδ, and PCNA localization at damage sites in confluent NHF after local UV irradiation (30 J/m 2 ) at time points as indicated. “Merge” refers to the combined image of DAPI and PCNA staining. (B) Immunolocalization of XPB, RPA, Polδ, and PCNA in NHF in the presence of HU and AraC at different repair times after 30 J/m 2 local UV irradiation. (C) Immunolocalization of XPB in confluent XP-A cells at different repair times after 30 J/m 2 local UV irradiation. (D) XPC and 6-4PP were visualized by immunostaining after local UV irradiation; cells were irradiated with 30 J/m 2 UV and incubated for either 30 min or 20 h.
