New micro-turbidimetric method for determination of protein in cerebrospinal fluid and urine.


We report a new micro-scale (0.1-mL sample) turbidimetric method for determination of protein by use of benzethonium chloride in alkali. The method is highly specific for protein, has a higher sensitivity than the classic method of Lowry et al., and shows satisfactory reproducibility and recovery. The turbidity produced in our method is the same for albumin and gamma-globulin and is more stable than in Meulemans' method (in which sulfosalicylic acid is used) or in the method of Bossak et al. (in which trichloracetic acid is used). In contrast to Pesce and Strande's method, there is no manipulative loss of protein.
