VZV ORF33.5 encodes a scaffold protein involved in the assembly of the viral capsid. ORF33.5 has the capacity to mediate ORF40 translocation into the nucleus of VZV-infected cells and exhibits a nuclear localization phenotype. ORF33.5 is 3′ coterminal with and produced by a proteolytic cleavage of a precursor protein ORF33. Our anti-VZV ORF33.5 antibody VZ 33,5.04 works in ELISA (on immunogen), in IF (on VZV infected cells) and each LOT is validated for Western blot where it specifically recognized a protein of 33kDa in lysates of VZV infected cells (described in J Virol. 2013 Jun;87(12):6943-54).
