INITIAL RATE PHOTOMETRIC METHOD FOR IMMUNOASSAY |
摘要 |
An initial rate photometric immunoassay method useful for detecting and quantifying analytes in various physiological fluids is disclosed. The method is carried out by combining in a liquid medium an undiluted sample of analyte-containing physiological fluid, such as serum, and an excess of an anti-analyte antibody. A substantially constant initial rate of increase of the liquid medium'sturbidity, due to the resulting immunoprecipitation reaction, is measured in real time and compared to a calibration curve prepared from known analyte concentrations to detect and quantify the analyte. Detection and quantification of numerous analytes including haptens, drugs and proteins, in a wide variety of physiological fluids can be rapidly carried out by the present method. |
