VZV ORF21 encodes a 115 kDa protein that is essential for viral replication in cell culture and is also expressed during, but is not required for establishment of latency in dorsal root and cranial nerve ganglia. During infection, VZV ORF21 protein localizes to both nuclei and cytoplasm of infected cells and, together with proteins encoded by VZV ORFs 20, 21, 23, 33, 40 and 41, forms the icosahedral nucleocapsid core of VZV virions. In addition, protease treatment and detergent solubilization experiments of VZV virions suggest that VZV ORF21 encoded protein is not associated with tegument of VZV particles. Our anti-VZV ORF21 antibody VZ 21.3.05 works in ELISA (on immunogen) and IF (on VZV infected cells), and each LOT is validated for Western blot (of VZV infected cell lysates), where it specifically recognizes a protein species of ~116 kDa, which corresponds well to the predicted size of ~115 kDa protein encoded by the VZV ORF 21 (described in J Virol. 2013 Jun;87(12):6943-54.).

Immediate-early 62 protein (IE62) is a homolog of herpes simplex type 1 (HSV-1) ICP4. These two proteins have conserved DNA bidnding domain,while not activation domain (J Virol 1993. 67: 4246-4251).
VZV ORF4 encodes an IE4 protein that acts as transactivator of several immediate early, early and late VZV genes. Dimerization of IE4 is required for its transactivation function.
VZV ORF23 encodes a 24 kDa small capsid surface protein that localizes primarily to cell nuclei during infection and is not essential for viral replication in cell culture, even though its absence disrupts the capsid assembly.
Open reading frame 37 (ORF37) of Varicella zoster encodes for envelope glycoprotein H (gH). VZV gH is a 118kDa type 1 transmembrane glycoprotein highly conserved among other alphaherpesviruses.
