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

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