Goose astrovirus (GAstVs) is an emerging pathogen of goslings that causes fatal gout, kidney hemorrhages, renomegaly, and high mortality. The GAstVs VP27 protein is an important capsid protein and a candidate for the development of diagnostic reagents. The aim of this study was to clone and express the VP27 gene for preparation of a specific monoclonal antibody (mAb). The VP27 protein was expressed and purified in the supernatant of Escherichia coli BL21. Then, the mAb was obtained with the hybridoma technique and named 2AF11. It was differentiated as IgG1 with the help of immunoglobulin subclass tests. This mAb can specifically recognize the VP27 protein in GAstVs-infected cells, as evidenced by western blot analysis and immunofluorescent assay. Furthermore, this mAb could also detect the VP27 protein in GAstVs-infected tissues, as demonstrated by immunohistochemistry. These findings indicate that this mAb has high diagnostic potential. Therefore, the newly produced anti-VP27 mAb, 2AF11, could be a useful tool as a specific diagnostic marker for GAstVs.
