Five albumin components designatcd s2e1, s3e1, s3e2, s3e3, and s3e4 were isolated from yellowtail plasma, by combination of Sephadex G-200 gel filtration and starch block electrophoresis. Component s2e1 showed a molecular weight of about 130, 000, and was composed of subunits of an approximate molecular weight of 25, 000. The remaining components whose molecular weights ranged from 56, 000-76, 000, were composed of single polypeptide chains. Components s2e1, s3e3, and s3e4 exhibited yellow, red, and orange colors, respectively. when dissolved in water. Component s2e1 was featured by a large amount of lipid up to 60%, and also by binding abilities with BPB and bilirubin. Components s2e1 and s3e3 showed methemalbumin-forming and hematin-binding abilities, the latter component being preferential in either ability. Sevin (l-naphthyl N-methylcarbamate) esterase activity was detected in s3e4 alone.
