EYFP-cattle XLF accumulated quickly at DSBs induced by laser microirradiation. (A)
The localization and accumulation of EYFP-cattle XLF at DSBs induced by 405 nm laser
irradiation were examined. (B) Imaging of living EYFP-cattle XLF-transfected MDBK
cells before (upper panel) and at 1 min after (lower panel) microirradiation. Left
panel, EYFP-cattle XLF; right panel, differential interference contrast images (DIC).
Arrowheads indicate the microirradiated sites. (C) Immunostaining of microirradiated
EYFP-cattle XLF-transfected cells with anti-γH2AX antibody. The cells were fixed and
stained with the anti- γH2AX antibody at 5 min postirradiation. Left panel,
EYFP-cattle XLF; center panel, γH2AX image; right panel, merged image. (D)
Time-dependent EYFP-cattle XLF accumulation in living cells (5-120 sec) after
irradiation. Upper panel, EYFP-cattle XLF; lower panel, differential interference
contrast images (DIC).
