  • 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.

Customer reviews and Q&As

In regards to the JCV VP1 Protein, ab74569. JCV Polyomavirus Major Capsid VP1 protein is supplied in the form of VLP (Virus-like particles). Actually it is a higher structure formed from pentamers, but not pentamers itself.

Thank you for contacting us.

JCV VP1 was purified assembled into virus like particles (VLPs).

VLP is the structure formed from pentamers, but in fact it is not pentamer or monomer form of VP1.

I hope this info...

Thank you for your reply. I can confirm that the antibody ab34756 will react with the SV40 VP1 protein ab74565. On the antibody datasheet in the section labelled "cross-reactivity", it notes that it does react with the VP1 protein of SV40. I hope this...
