Identification of nka and nkcc. (a) The expression profiles of nka in the different tissues including the gill, hindgut, hepatic caecum, skin, notochord, and muscle. (b) The expression profiles of nkcc in the different tissues. (c) Expression of nka in the gill of amphioxus cultured under 25‰ or 30‰ salinity. (d) Expression of nkcc in the gill of amphioxus cultured under 25‰ or 30‰ salinity. The ef1α was chosen as internal control for normalization. Data were from 3 independent experiments and expressed as mean ± SEM. The symbol shows .
