1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing. -
纯化方法
- The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

应用备注
- T-ag purified with PAb 101 has been shown to retain helicase activity. T-ag is immunoprecipitated as a single or multiple bands between about 80-95 kD depending on post-translational modifications. SV40-transformed cells such as COS-7 (ATCC CRL 1651) are suggested as positive controls. Any cell line that is not SV40-transformed or SV40-infected can be used as a negative control.

背景
- Simian virus 40 is a small DNA virus encoded by 5.2 kb of double-stranded DNA. SV40 large T antigen (T-ag) is a multifunctional ~85 kD phosphoprotein, which is the sole viral protein required for SV40 replication. All other factors are provided by the infected host cell. In addition to its role in SV40 DNA replication, T-ag also causes transformation of susceptible cell lines. Studies of various mutant T-ag proteins have shown that the replication and transformation fractions of T-ag can be separated. The multifunctional nature of this protein has resulted in its use as a model system in a wide variety of disciplines. SV40 T-ag exercises negative regulation on the transcription of SV40 early mRNA by feedback inhibition and exerts positive regulation on transcription from the late promoter. In addition to transcriptional regulation, T-ag is involved in viral DNA replication. Specific biochemical functions required for DNA synthesis that are inherent to the T-ag include high-affinity binding to sites within the viral origin of DNA synthesis, and ATPase and helicase activities. Other functions attributed to T-ag include cellular transformation, induction of cellular DNA synthesis, induction of rRNA synthesis and provision of a host-range function for viral replication. However, all functions of T-ag are influenced by a wide range of post-translational modifications including phosphorylation, glycosylation, acetylation, acylation and adenylation. T-ag exists in monomeric as well as polymeric forms and associates with the tumor suppressor proteins p53 and Rb (retinoblastoma protein). Most of T-ag is transported to the nucleus, while a small fraction is localized at the cell surface. PAb 101 recognizes a C-terminal epitope within the last 190 amino acids of T-ag. PAb 101 was originally known as Clone 7. Studies have suggested that PAb 101 binds the strongest to mature T-ag. PAb 101 (i.e., Clone 7) was developed along with a panel of monoclonal antibodies where SV40-transformed BALB/c mouse cell lines (SVT2 or B4) were used as immunogens. The specificity of the antibody was originally characterized by a variety of techniques using SV40-infected and SV40-transformed cells.
