Anti-GTF2A1 Antibody

Raised in rabbit and purified as a polyclonal reagent, this Antibodies.com primary antibody targets GTF2A1 (also known as TFIIA subunit 1), a transcription initiation factor involved in RNA polymerase II-mediated gene expression. The reagent is supplied at 1.0 mg/mL in a 50 µl volume and is unconjugated, making it well suited to standard immunodetection workflows. It was generated against a recombinant human GTF2A1 immunogen and detects the endogenous level of total GTF2A1 protein, with reactivity confirmed for human samples. Validated applications include Western blot and immunohistochemistry on paraffin-embedded tissue; representative IHC data supplied by Antibodies.com show staining of human thyroid cancer sections at a working dilution of approximately 1:200. The host species is rabbit, the clonality is polyclonal, the isotype is IgG, and the formulation consists of phosphate-buffered saline (without Mg²⁺ and Ca²⁺) at pH 7.4, supplemented with 150 mM NaCl, 0.02% sodium azide, and 50% glycerol. For stability, the vial is shipped at 4 °C and should be aliquoted and stored at –20 °C upon arrival, with repeated freeze/thaw cycles avoided. Researchers studying basal transcription, GTF2A1 function, or chromatin-associated transcriptional regulation will find this reagent a practical tool for both protein-level expression studies and tissue-localization experiments.
