Fig. 4. Two-dimensional electrophoretic separation of ³⁵S-labeled proteins after 30-min heat shock at 40.5°C and 3 h of recovery at 25°C. Species and strains are noted. Labels refer to molecular masses of Drosophila heat-shock proteins; 70c represents constitutively expressed Hsp70 family members. The box in the Hsp70 region for D. lummei strain 1109 represents the region detailed in Fig. 6. See Garbuz et al. (2002) for additional results after less-severe heat shock.
