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.
4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
Purification The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name TFIIB (GTF2B Antibody Abstract)
Background TFIIB is a ubiquitous factor required for transcription initiation by RNA polymerase II. Studies suggest that TFIIB serves as a bridge between the TATA-binding factor (TFIID) and RNA polymerase II during pre-initiation complex assembly and that TFIIB can be a target of acidic activators. An essential component of the machinery that transcribes protein-coding genes, the three-dimensional structure of the human TFIIB appears to consist of two direct repeats that adopt similar alpha-helical folds, conferring pseudo-twofold symmetry. An extensive, central basic surface, including an amphipathic alpha helix, is critical to the function of TFIIB as a bridge between the TBP-promoter complex and transcription factors. TFIIB has a calculated molecular weight of 33 kD and has been reported to be observed to migrate between 33-40 kD. This antibody is routinely tested by western blot analysis.
