TFIIB Antibody (D-12) is a mouse monoclonal IgM antibody that detects TFIIB in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). TFIIB plays a crucial role in the transcription initiation process by serving as a bridge between the TATA-binding protein (TBP) and RNA polymerase II, facilitating the assembly of the transcription pre-initiation complex. This interaction is vital for the accurate transcription of protein-coding genes, as TFIIB ensures that RNA polymerase II is properly positioned at the promoter region, allowing for the precise regulation of gene expression. TFIIB′s importance extends beyond its structural role; TFIIB also influences the recruitment of additional transcription factors and co-activators, thereby modulating the transcriptional response to various cellular signals. Anti-TFIIB antibody (D-12) enables researchers to gain insights into the dynamics of transcription regulation and the intricate mechanisms that govern gene expression in eukaryotic cells.
