SV40 T antigen-transformed human embryonic kidney (293T) cells: 293T cells may be obtained from the American Type Culture Collection (ATCC; catalog no. CRL-11,268).. Culture medium: Dulbecco's modified Eagle's medium (DMEM) supplemented with 10% fetal calf serum, 100 U/ml penicillin and 100 μg/ml streptomycin.

Mutant large T antigens containing only the first 138 to 140 amino acids were unable to bind to the SV40 origin of DNA replication as were large T antigens containing at their COOH termini 96 or 97 amino acids encoded by the long open reading frame located between 0.22 and 0.165 map units (m.u.).

Moreover, LMP1 regulated p53 both at transcriptional and translational level. These results strongly indicate that the association of topo I with these six residues in T antigen is essential for DNA replication. The 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.

Interferes with histone deacetylation mediated by HDAC1, leading to … version of the SV40 large T antigen.5,6 The SV40 large T antigen is known to be capable of transforming human and rodent cells in vitro and in vivo. Also SV40-transformed human cells are able to produce tumors when administered to nude mice.7,8 Therefore, the … 2005-11-21 2016-03-31 2017-04-14 2009-02-20 2020-03-04 SV40 T antigen has been shown to be the most simple and reliable agent for the transfromation of many different cell types in culture. The mechanism of SV40 T antigen in cell immortalization is well studied. For the most part, viral genes achieve immortalization by inactivating the tumor suppressor genes (p53, Rb and others) that can induce a replicative senescent state in cells. Plasmid pBABE-puro SV40 LT from Dr. Thomas Roberts's lab contains the insert SV40 LT and is published in Cancer Cell. 2003 May .

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 …

Secondary Because SV40 T antigen stimulates replication at its ori, we tested plasmid replication in these transfected cell lines. The immortalized cell lines that showed low G418r transformation frequencies after transfection with pSV2Neo showed high levels of plasmid replication, while the T-SV-HUC that showed high G418r transformation frequencies failed to replicate pSV2Neo.

Unreviewed-Annotation score: -Protein predicted 2017-02-24 · SV40 T Ag Antibody (H-1) is a monoclonal anti-SV40 T Antigen antibody that detects SV40 SV40 T Ag by WB, IP, IF, IHC(P) and ELISA. Cited in 4 publications SV40 T-antigen from simian virus (insect cells, ≥ 80% SDS-PAGE); The large T antigen (TAg) of Simian virus 40 acts as an initiator of DNA replication, participates in cellular transformation, and induces cell growth; Inactivation of cellular p53 is a crucial step in carcinogenesis. Accordingly, p53 is inactivated in most human cancers by different mechanisms. In cells infected with DNA tumor viruses, p53 is bound to the viral tumor antigens (Tag). The current “dogma” views the Tag-p53 complexes as a way of sequestering and inactivating p53.

SV40 large T antigen (Simian Vacuolating Virus 40 TAg) is a hexamer protein that is a dominant-acting oncoprotein derived from the polyomavirus SV40. TAg is capable of inducing malignant transformation of a variety of cell types.
