Figure 1. UV-irradiation protocol of XB2 mouse keratinocytes.

Figure 1

(A) Schematic representation of the UV (254 nm) treatment time course. Cells were irradiated with eight successive 10 J/m2 UV pulses lasting 3 sec each at 15 min intervals, and harvested at indicated times after the last UV pulse. (B) Viability of XB2 keratinocytes after UV-irradiation (4×5 J/m2 or 8×10 J/m2) was determined by the MTT assay.
