VZV ORF12 (UniProtKB – Q6QCP3) encodes a tegument protein, an orthologue of HSV1 protein UL46 which is highly conserved among alphaherpesviruses. Its function is not known, but Che et al. showed that ORF12 gene is dispensable and can be deleted without any apparent effect on VZV replication in vitro (J. Virol. 82, 5825–5834 (2008)). Our anti-VZV12 antibody VZ 12.04 showed that during infection VZV ORF12 protein localizes to Golgi network. Our anti-VZV12 antibody VZ 12.04 works in ELISA (on immunogen), IF (on VZV infected cells) and each LOT is validated for Western blot of VZV infected cell lysates, where it recognizes a protein of ~80 kDa (described in J Virol. 2013 Jun;87(12):6943-54.).
