The simian virus 40 (sv40) tumor antigen (T-antigen) and tumor-specific transplantation antigen (TSTA) have been partially purified and studied to clarify their relationship.

SV40 status was correlated with clinico-pathological data. T/t-ag immunostaning was detected in the tumor cells in 31/56 (55.4%) osteosarcoma cases. SV40 Large T Antigen ELISA Kits The ELISA (enzyme-linked immunosorbent assay) is a widely used application for detecting and quantifying proteins and antigens from various samples. Target-specific ELISA kits are available from a variety of manufacturers and can help streamline your immunodetection experiments. SV40 T Antigen Cell Immortalization Kit Product Name SV40 T Antigen Cell Immortalization Kit Description It is well known that primary cells only undergo a pre-determined and finite number of cell divisions in culture. After limited population doublings (the number of which SV40 Large T Antigen. SV40 large T antigen is a viral protein required for viral DNA replication, and a potent transforming protein.

Activation of the SV40 late promoter: Direct effects of T antigen in the absence of viral DNA replication. Janis M. Keller.

This report documents the requirement for viral small-t (ST) antigen in large-T (LT)-driven transformation of primary fibroblasts, a requirement The search for SV40 was performed by immunohistochemistry using the Pab108 antibody for the detection of the viral oncoproteins: large T antigen and small t antigen (T/t-ag). SV40 status was correlated with clinico-pathological data. T/t-ag immunostaning was detected in the tumor cells in 31/56 (55.4%) osteosarcoma cases.

SV40 T antigen is encoded by the early region of the SV40 genome. The large T antigen binds DNA, and complexes with a 53,000 dalton cellular protein, p53, which is required for initiation of viral DNA replication during lytic growth.

Adeno-associated virus (AAV) inhibits the induction of host DNA synthesis by simian virus 40 (SV40) large-tumour (T) antigen, mediated through AAV-encoded 'Rep' regulatory proteins. Rep proteins are normally synthesized by AAV-infected cells only in the presence of adenovirus. pSV2Neo,aplasmidthatcontains thewild-type simianvirus 40 (SV40) origin ofreplication (ori), is widely usedin mammaliancell transfection experiments.WeobservedthatpSV2Neotransformstwonontumorigenic SV40-immortalizedhumanuroepithelial cell lines (SV-HUCandCK/SV-HUC2)to G418resistance (G418r) at afrequencylowerthan that atwhichit transforms SV-HUCtumorigenic derivatives (T-SV-HUC). SV40 large tumor antigen (Tag) was investigated by immunoprecipitation, silver staining, and Western blot analysis in 65 brain tumor cases and 8 cases of normal brain tissue. Tag‐p53 and Tag‐pRb complexes were screened by immunoprecipitation and Western blot analysis in 18 and 15 Tag positive tumor tissues, respectively. One of the most commonly used immortalizing genes is SV40 T antigen –. We and others previously used retroviral vector-mediated expression of SV40 T antigen to immortalize primary cells –.

The SV40 large T antigen from the SV40 virus is the most well-studied member of the LTag family. SV40, also known as Macaca mulatta polyomavirus 1, natively infects monkeys and does not cause disease; however, it is oncogenic in some rodents and can immortalize some human cells in primary cell culture .
