Fig. 1. Western blot analysis of (A) NKCC1a and (B) NCC in the gills of Mozambique
tilapia acclimatized to freshwater (FW) or seawater (SW), and (C,D) a
preabsorption test for NCC immunofluorescence staining in the yolk-sac
membrane of freshwater-acclimatized tilapia embryos. The NCC-positive
immunoreactivity (C) is completely abolished by preabsorbing antibody against
NCC with the corresponding antigen peptide (D). Molecular mass standards are
indicated (kDa). Scale bar, 10 µm.
