To reveal neurons containing the calcium-binding protein CB, we used the CB38a anti-CB rabbit polyclonal antibody from Swant (CB38a; RRID AB_10000340) at a dilution of 1:10,000. The pattern of staining within the neurons of the basal forebrain, diencephalon, and pons of the harbor porpoise was similar to that seen in other mammals (Gritti et al., 2003 (link); Bunce et al., 2013 (link); Bhagwandin et al., 2013 (link)).
