Abstract: | IgG1 is separated from its impurities in cell growth medium under simple CZE conditions without specific sample pretreatment. Linearity, limit of quantitation, limit of detection, precision and accuracy for the method are demonstrated. The quantitation for IgG1 in the cell growth medium is obtained by generating a calibration curve and by using standard additions. This CE method can offer a good alternative to conventional HPLC methods. Attempts are also made to separate the heterogeneous species in monoclonal antibodies using both CZE and MECC. |
