Stains / Test Description

Simian Virus 40 (SV40) is a polyomavirus that is found in both monkeys and humans. Like other polyomaviruses, SV40 is a DNA virus that has the potential to cause tumors. SV40 is believed to suppress the tumor-suppressing p53 in humans. A mutated p53 gene may contribute to uncontrolled cellular proliferation, leading to a tumor. The hypothesis that SV40 might cause cancer in humans has been a particularly controversial area of research. Some research has suggested that SV40 is associated with brain tumors, bone cancers, non-Hodgkin lymphoma and malignant mesothelioma. This antibody shows cross-reactivity to BK and JC virus, and some use it a surrogate to detect these viruses.
