IIB1_AF594_TFIIB_Antibody_IF_102915
HeLa cells were fixed with 2% paraformaldehyde (PFA) for 10 minutes, permeabilized with 0.5% Triton X-100 for five minutes, and blocked with 5% FBS for 30 minutes. Then the cells were intracellularly stained with 2 µg/ml Alexa Fluor® 594 conjugated (red) TFIIB Antibody (clone IIB1) in blocking buffer overnight at 4°C. Actin filaments were labeled with Alexa Fluor® 488 Phalloidin (green). Nuclei were counterstained with DAPI (blue). The image was captured with a 60X objective.

Description

TFIIB is one of the ubiquitous transcription factors required for transcription initiation by RNA polymerase II. It plays an important role in pre-initiation complex assembly, which provides a bridge between promoter-bound TFIID and RNA polymerase II. Moreover, TFIIB also directly modulates the catalytic center of RNA polymerase II.
