Analysis of hsp70 protein levels in embryos exposed to high doses of UV-B. Western blot of total lysates from unexposed (0 J/m2) and exposed (200, 400 and 800 J/m2) embryos harvested 48 h after irradiation, and reacted with anti-hsp70. The positions of the molecular markers (97 and 66 kDa) are indicated on the left. The histogram shows result obtained by densitometric scannings of the filter, band intensities are reported in arbitrary units
