Abstract: A DNA coding for an entire or a part of an antigen protein of the rinderpest virus; a protein for the production of the DNA comprising the steps of preparing an mRNA from the rinderpest virus, preparing a cDNA library from the mRNA, selecting a cDNA coding for the target protein from the cDNA library, and cloning the selected cDNA in a cloning vector; and a protein for the production of the antigen protein of the rinderpest virus comprising the steps of transfecting a vector containing the DNA coding for the target protein into animal cells, culturing the animal cells to produce the antigen protein, and recovering the target protein from the cell culture.
