Figure 3. Phylogenetic analysis of Na+:K+:2Cl- cotransporter 1b (Nkcc1b) from the brain of Monopterus albus .
A phylogenetic tree to illustrate the relationship between Nkcc1b from the brain of M. albus and Nkcc/NKCC of selected vertebrate species. Numbers presented at each branch point represent bootstrap values from 100 replicates. Strongylocentrotuspurpurtus Nkcc is used as the outgroup for the phylogenetic tree for Nkcc.
