Abstract:

In order to study the function of canine distemper virus (CDV) V protein,V gene fragment was inserted into the pGEX-6p-1 vector,and then pGEX-6p-1-CDV-V recombinant expression plasmid was obtained.Purified V protein immunized BALB/c mice to prepare the positive serum.Meanwhile,to confirm the distribution of V protein and subcellular localization with confocal laser technology,a eukaryotic expression recombinant plasmid pcDNA3.1-CDV-V was built,then transfected into Vero cells.The results showed that V protein was successfully expressed and the positive serum was prepared.The recombinant plasmid pcDNA3.1-CDV-V was expressed in Vero cells and mainly expressed in cytoplasm.The results laid a function for functional studies of CDV V protein.

Key words: canine distemper virus; V protein; prokaryotic cell; subcellular localization
