A Simple Method for the Estimation of Total Protein Content of Plasma and Serum. Ii. the Estimation of Total Protein Content of Human Plasma and Serum by the Use of the Falling Drop Method.
چکیده
An instrument for the accurate estimation of serum protein which has the simplicity of a hemoglobinometer has an obvious place in medicine. Peters and Van Slyke (1) have reviewed the many physical methods which have been tried and conclude that the specific gravity is the most accurate. They find the colorimetric method liable to errors up to 10 per cent. Moore and Van Slyke (2) found the relationship between the specific gravity and protein content of human heparinized plasma could be expressed by the equation of a straight line: P=343 ( G1.0070)
