Western blot of cytosolic and nuclear extracts of R64-containing CHO-K1 cells. R64 was detected using rabbit anti-R42 antiserum, alkaline phosphatase-conjugated goat anti-rabbit IgG, and the phosphatase substrate 5-bromo-4-chloro-3-indolyl phosphate. Lane 1: molecular mass markers; lane 2: synthetic R64 (calculated molecular mass, 7611 Da; 500 ng applied); lanes 3 and 7: nuclear and cytosolic cell extract controls; nuclear and cytosolic extracts of cells incubated with 1.3 μM R64 (lanes 4 and 8), 1.7 μM R64 (lanes 5 and 9), and 2.3 μM R64 (lanes 6 and 10), respectively.
