Abstract
The aim of this study was to prepare and identify a monoclonal antibody that binds the viral proteins 7 (VP7 protein) of human group B rotavirus (GBRV) and to describe its immunologic characterization. Human group B rotavirus vp7 gene was successfully ligated into pGEX-KG vector and transformed into Escherichia coli TOP10 cells. The glutathione S-transferases (GST)-fusion protein GST-VP7 was induced by Isopropyl β-D-1-thiogalactopyranoside (IPTG) and immediately purified to immunize BALB/c mice. Splenocytes were then prepared from the immunized mouse and fused with SP2/0 myeloma cell line. In the end we obtained one positive hybridoma cell line stably secreting monoclonal antibody against GST-VP7 protein by indirect enzyme-linked immunosorbent assay (ELISA) and limiting dilution. The production of the monoclonal antibody against GBRV will benefit the further study of GBRV's structures and functions and also lay a solid foundation for the research of disease prevention, clinical diagnosis, and treatment.
