Clone KH95
Isotype IgG2a
Characteristics 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.
Purification Purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name E2F-1
Background The transcription factor E2F was originally characterized as a sequence-specific DNA-binding factor bound to the adenovirus E2A promoter. E2F-binding sites have now been identified in cellular promoters for genes involved in growth regulation, including c-myc, N-myc, Cdc2 and cyclin A. They have also been identified in promoters for genes whose products are required for DNA synthesis and replication, such as DNA polymerase a, thymidine kinase, thymidylate synthase, and dihydrofolate reductase. When bound to DNA, E2F has been found in complexes with key regulators of cell proliferation including the retinoblastoma protein (Rb) and the Rb related proteins, p107 and p130. Like a variety of other transcription factors, E2F binds to DNA as a heterodimer. The protein E2F-1 has E2F-like properties, it mediates E2F-dependent trans-activation and binds to underphosphorylated Rb. E2F dimerizes with DP-1, a protein which also has E2F-like properties. This dimerization leads to increased DNA binding activity and enhanced transcriptional activity. It is thought that E2F-1/DP association forms an active E2F” transcription factor. E2F-1 migrates at a reduced molecular weight of ~60 kDa. Clone KH95/E2F (also referred to as KH95) recognizes an epitope between amino acids 342 and 386 of human E2F-1. It cross reacts with mouse and rat E2F-1. Full length, bacterially expressed, recombinant histidine-tagged human E2F-1 (amino acids 1-437) was purified and used as immunogen. Positive tissue culture supernatants were identified by immunoprecipitation of [35S]methionine-labeled, in vitro synthesized E2F-1 protein.
