The protein contains the CMV pp28 immunodominant regions, amino acids 130-160. The protein is purified by proprietary chromatographic technique.
Background: Human cytomegalovirus (HCMV), a member of the herpesvirus family, demonstrates cell specificity for virus assembly and release. The human cytomegalovirus pp28 is a myristylated phosphoprotein that is a constituent of the virion. The pp28 protein is positioned within the tegument of the virus particle, a protein structure that resides between the capsid and envelope. In the infected cell, pp28 is found in a cytoplasmic compartment derived from the Golgi apparatus, where the virus buds into vesicles to acquire its final membrane.
Specificity: Immunoreactive with sera of CMV-infected individuals.
