Anti-TFIIE-β Antibody

TFIIE-β (also known as GTF2E2) is the small subunit of the general transcription factor TFIIE, which is recruited to the pre-initiation complex and required for RNA polymerase II-dependent transcription in eukaryotic cells. This rabbit polyclonal antibody, supplied by Antibodies.com, was raised against TFIIE-β and is validated for Western blot (WB) and immunohistochemistry (IHC) workflows. The unconjugated immunoglobulin is provided as a 100 µl aliquot at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.2, ready to pair with a user-selected secondary reagent or detection chemistry. It shows reactivity with human, mouse, and rat samples, supporting studies that span tissue culture cells and rodent tissue sections. The polyclonal format recognizes multiple epitopes on the target, which is useful when working with denatured lysates or fixed specimens, and allows researchers to apply their own labelled secondary antibodies for chemiluminescent, fluorescent, or chromogenic readouts.
