Figure 4.
Immunofluorescence localization of anti-TSC antibody in cortical sections from rats fed control (A) and low-NaCl (B) diets. An increase in TSC labeling of distal convoluted tubules from rats on the low-NaCl diet is detected compared with rats fed the control diet. Labeling conditions and confocal microscope settings are identical for A and B. (Bar, 25 μm.)
