Figure 1. Expression of ENaC subunits in rabbit conjunctiva in immunohistochemical stainnings. ENaC-α (A and I), ENaC-β (B and J), and ENaC-γ (C and K) were positive at apical layer of conjunctiva. As a positive control, ENaC-α (E and M), ENaC-β (F and N), and ENaC-γ (G and O) were positive at inner medullas of kidney. Isotype control specimen showed no positive staining in conjunctiva (D and L) and kidney (H and P). Scale bars in A-H represent 20 μm, and scale bars in I-P represent 40 μm.
