A comparison of five of the methods commonly used to measure protein concentrations in fish sera
The concentration of protein in the sera of rainbow trout, Salmo gairdneri , brown trout S. trutta and Atlantic salmon S. salar has been measured by six standard techniques viz refractometry, copper sulphate specific gravity, automated and manual biuret, optical density and Lowry et al. phenol reage...

| Summary: | The concentration of protein in the sera of rainbow trout, Salmo gairdneri , brown trout S. trutta and Atlantic salmon S. salar has been measured by six standard techniques viz refractometry, copper sulphate specific gravity, automated and manual biuret, optical density and Lowry et al. phenol reagent and the results compared. Good correlation was obtained in most cases and interconversion formulae are given between each method in the three salmonid species. The concentrations obtained with the refractometer and optical density methods were approximately one and a half times those obtained with the others. |
