Anti-TF2E2 Antibody

This unconjugated rabbit polyclonal antibody from Antibodies.com targets TF2E2, the ~34 kDa beta subunit of general transcription factor TFIIE. TFIIE partners with RNA polymerase II at the promoter and supports the transition from a closed to an open promoter complex and subsequent promoter clearance during mRNA transcription initiation, making TF2E2 a useful marker for studies of transcription-coupled repair, chromatin dynamics, and RNA polymerase II-dependent gene expression.

The reagent is validated for Western blot (WB) and immunohistochemistry (IHC) applications and cross-reacts with both human and mouse samples, supporting comparative work between cultured mammalian cells, tissue lysates, and fixed tissue sections. Supplied as a 100 µl liquid aliquot of polyclonal antiserum raised in Rabbit, the antibody is unconjugated to give researchers flexibility over secondary detection chemistries or custom conjugation strategies.

For handling, aliquot the vial upon receipt to limit freeze-thaw cycles, store refrigerated for short-term use, and protect from light. Each lot is quality-controlled by Antibodies.com to deliver consistent antigen recognition and signal performance across the listed applications.
