Antibody-based mieroarray is a novel proteomic technology that can meet the requirements. In this study, we developed an antibody microarray for WSSV-detection in a specific and parallel way at multiple samples. First, seven slides each with different modifications were characterized by atomic force microscope, and were compared in the efficiency of immobilizing proteins. Of the seven, 3-dimensional structured agarose gel-modified slides were chosen appropriate for the microarray for having higher signal value and superior spot size. A purified rabbit anti-WSSV antibody was arrayed as the capture antibody of the microarray on the agarose gel-modified slides, and then the mieroarray slides were incubated in the tissue homogenate of sampled shrimp and the antibody-antigen complex was detected by Cy3-conjugated anti-WSSV monoclonal antibody. The results were measured by a laser chipscanner and analyzed with software. To obtain satisfied fluorescence signal intensity, optimal conditions were searched. The detection limit of the antibody microarray for WSSV is 0.62μg/mL, with a woven long shelf life for 6 months at 4℃ or 8 months at -20℃. Furthermore, concordance between antibody microarray and traditional indirect ELISA reached 100% for WSSV detection. These results suggest that the antibody microarray could be served as an effective tool for diagnostic and epidemiological studies of WSSV.展开更多

We present a case of Dandy-Walker syndrome diagnosed antenatally. The assoiacted anomalies are reviewed, and the value of antenatal diagnosis is discussed.展开更多
