Anti-TFIIE-β Antibody

This rabbit polyclonal reagent from Antibodies.com targets the β subunit of general transcription factor TFIIE (gene symbol GTF2E2), a basal transcription factor that joins the RNA polymerase II preinitiation complex, recruits TFIIH, and supports promoter DNA melting at the start of transcription. The antibody is supplied as 50 µl of liquid at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.2, and is left unconjugated so end users can apply their own detection chemistries.

Validated uses include Western blot and immunohistochemistry on human, mouse, and rat samples, allowing comparative work across common laboratory models. Polyclonal recognition of multiple epitopes on TFIIE-β can help when probing denatured lysates or fixed tissue sections. The host species is rabbit, and the reagent is intended for research use only. For handling, refrigerate the vial between uses and aliquot before freezing if longer-term storage is needed; protect from light and limit freeze-thaw cycles to preserve activity.
