Abstract | This study represents a label-free immunoassay for carcinoembryonic antigen (CEA) by microfluidic biosensor based on imaging ellipsometry (BIE) and its application is further validated by clinic sera. The sandwich format of analysis configuration was adopted, in which Rat-mAb was served as capture antibody, rabbit anti-CEA polyclonal antibody (rabbit-pAb) as detection antibody and goat anti-rabbit IgG (goat-IgG) as an enhancer added to increase detection signal. The methodology includes rat-mAb concentration screening, rabbit-pAb and goat-IgG concentration optimization, creation of dose-response curve and determination of cutoff value. Results show the linear range is from 4.0-64.0 ng/ml with a lower limit of 1.0 ng/ml (S/N = 3). Application of the BIE to clinic samples demonstrated that the relation coefficient is 0.94 and substantial agreement with the results of ECLIA's (Kappa = 0.733,U = 4.35 > U-0.01). The proposed method exhibits the potential for application. |
