Abstract

The present invention provides a preparation method for PCV2 capsid protein and a pharmaceutical composition containing said capsid protein. The method of the present invention uses a novel arabinose-induced expression vector and thereby improves the synthesis efficiency of said PCV2 capsid protein. On the other hand, the present pharmaceutical composition combines said capsid protein and other favorable components at a proper ratio so that achieves excellent immune-inducing effects.
