A researcher is examining the distribution of an ion channel protein in
the kidney. She incubates slices of kidney tissue in a dilute solution of
a specific antibody directed against the protein, then uses the
immunoperoxidase method to localize the ion channel proteins.
She notes the presence of brown pigment in a population of epithelial
cells, which on closer examination, have a brush border. The researcher
concludes that the protein is probably present in cells of the
A. collecting duct
B. deep portion of loop of Henle
C. distal convoluted tubule
D. glomerulus
E. proximal convoluted tubule

Yep, I agree. The PCT is the only area in the kidney with epithelial cells with a brush border, right?
