ADHR1 24 h self-cleavage after UV irradiation in the absence or presence of montmorillonite. (A): UV-irradiation in the absence of clay; (B): UV-irradiation in the presence of clay; (C) and (D): control 24 h self-cleavage reaction of not-irradiated ADHR1, in the absence and presence of montmorillonite, respectively. Arrows on the left indicate the two bands probably coming from UV-induced cross-linkages. FL: full-length ADHR1 molecule, 5'F: ADHR1 5' fragment of cleavage. Gel images were over-exposed to highlight the low-intensity bands.
