Figure 4. Oatp4c1 localization in paraformaldehyde-fixed paraffin-embedded rat kidney tissue sections.

Figure 4

Paraformaldehyde-fixed paraffin-embedded kidney sections were stained with antibodies as indicated. Following staining with PA1343 antibody, color development with NovaRed signifies Oatp4c1 staining (A). Sections were double-stained with PA1343 (B, C, red) and the proximal tubule marker AQP1 (B, green) or the distal tubule marker calbindin (C, green). Nuclei (blue) were stained with DAPI (Magnification: 4× (A), 10× (B, C)).
