Immunofluorescent analysis of XPC (green) showing staining in the nucleus and cytoplasm of NIH-3T3 cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a XPC polyclonal antibody (Product # PA3-956) in 3% BSA-PBS at a dilution of 1:100 and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a flourescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.

PA3-956 detects XPC in human and mouse cells.
PA3-956 has been successfully used in Western blotting and ICC/IF procedures. By Western blot it detects a ~125 kDa protein representing XPC.
The PA3-956 immunogen is two synthetic peptides, individually conjugated to the C-Terminus and N-Terminus respectively of human XPC.
XPC is a damage recognition/structure distortion factor used in nucleotide excision repair (NER). XPC exhibits the strongest affinity for damaged DNA, and showed a remarkable preference to UV-damaged DNA. It has been suggested as the initiator of global genome NER, and a recent immunohistochemistry study also strongly supports a role for XPC as a global initiator in repair. XPC is also involved in the recruitment on TFIIH to damaged DNA.
