Human cytomegalovirus is a ubiquitous herpes virus. The primary infection usually occurs in childhood where it most often is asymptomatic. After initial exposure, the virus establishes a life-long infection. In neonates, and in immunocompromised individuals, such as AIDS patients and transplant recipients, HCMV can cause severe life-threatening infections, and it is the most common cause of viral birth defects. Antibody CCH2 reacts with an early nuclear protein identical with the non-structural DNA-binding protein p52. Antibody DDG9 reacts with an immediate early nuclear protein of about 76kD. For both antibodies, the reactivity persists also at later stages during the HCMV infection where the localization is less distinctly nuclear and appears to be in the cytoplasm. Laser confocal microscopy, however, shows that the reaction is limited to the nuclear membrane.
