چکیده انگلیسی
Monoclonal anti-idiotypic antibody (Mab2-5G2) raised against idiotypic antibodies to membrane glycoprotein GP5 of porcine reproductive and respiratory syndrome virus (PRRSV). The variable regions of the heavy chain (VH) and light chain (VL) of Mab2-5G2 were cloned and connected with a (Gly4Ser)3 linker. The recombinant scFv gene was cloned into the pEasy-E1 vector and expressed in E. coli as inclusion bodies. The expressed scFv-His proteins renatured in a pH and urea gradient buffer retained the same immunological properties as that of Mab2-5G2. Renatured scFv-His protein retained the same characteristics as that of Mab2-5G2 by recognizing and binding to Marc-145 cells. Furthermore, renatured scFv-His along with Mab2-5G2 were used to immunize rabbits to produce anti-anti-idiotypic antibodies (Ab3) that neutralized PRRSV infection of Marc-145 cells. These results demonstrated that the expressed scFv-His protein possessed the same characteristics of Mab2-5G2 and will be suitable for future investigations of Mab2-5G2 antibody structure and its ability to interact with potential PRRSV cellular receptor as well as immunological properties against PRRSV infection.
