Abstract
As one of the viral proteins expressed in the immediate-early phase of HSVI infection, ICP22 functions in the regulation of viral replication. However, it is difficult to produce specific antibody against ICP22 protein with homology of antigenicity in this protein. Based upon prediction of antigenicity of ICP22, a peptide of 1-36 amino acids was thought to possess a specific antigenic epitope, which was expressed as a fusion protein with GST. The antibody, raised in mice immunized with a purified fusion protein, was able to recognize ICP22 expressed in eukaryotic cells. Analysis with this antibody suggested a nuclear locatization of ICP22 and specific punctuative structure in cells.
