Albumin, as a percent of total proteins in both the coelomic
serum and the blood serum, was determined for four groups of
developing Rana catesbeiana tadpoles by cellulose acetate electrophoresis.
Also, using Folin phenol reagent, the total protein of
each the blood serum of metamorphosing tadpoles and the coelomic
serum...
