  • Relevance
    The human polyomavirus JC virus (JCV) infects greater than 80% of the human population. The JC virus is a small (38-40 nm in diameter) double stranded, circular DNA virus covered by an icosahedral capsid. Infection with JCV is asymptomatic and it occurs in early childhood. After the primary infection, the virus remains in latent state in the kidney, until it's reactivation under immunosuppressive conditions to result in Progressive Multifocal Leukoencephalopathy (PML), a fatal demyelinating disease. 70% of all HIV-1- infected patients will exhibit neurological disorders and between 5 and 8% of all HIV-1-infected patients will develop PML. Similar to other polyomaviruses, JCV can cause tumors when intracerebrally inoculated at high titers into developing rodent. Several reports suggest the association of viruses, especially of the polyomavirus family with different types of human brain tumors. Tumorigenecity of JCV is most likely induced by the viral early gene product T-antigen. T-antigen has the capacity to interact with several tumor suppressor proteins, most notably p53, and functionally inactivate these proteins.


  • Immunoblot of recombinant major capsid protein VP1 (500 ng per lane) of human polyomavirus JCV using monoclonal antibody ab34756 at a concentration of 1 µg/mL.

  • ab34756 staining Human Polyoma virus JCV capsid protein VP1 in human fetal glial cell (SVG-A) by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with methanol and blocked with 2% BSA for 30 minutes at 22°C. Samples were incubated with primary antibody (1/1000 in PBS + BSA) for 1 hour at 37°C. An Alexa Fluor® 488-conjugated goat anti-mouse IgG (H+L) polyclonal (1/1000) was used as the secondary antibody.
