Anti-TFIID Antibody

This Rabbit polyclonal reagent from Antibodies.com targets the general transcription factor IID (TFIID) complex, the multiprotein assembly that contains the TATA-binding protein (TBP) and TBP-associated factors (TAFs) responsible for recruiting RNA polymerase II to core promoter regions. The unconjugated antibody is supplied as a 100 µl vial volume, providing enough material for multiple Western blots, immunohistochemistry runs, or immunofluorescence experiments.

Validated for WB, IHC, IF, and ELISA workflows against human, mouse, and rat samples, the reagent enables comparative studies of basal transcription machinery across standard laboratory model organisms. As an unconjugated polyclonal antibody raised in Rabbit, it can be paired with custom secondary labels, fluorophores, or HRP substrates to match the detection chemistry of a given protocol.

Refrigeration and protection from light preserve activity through routine benchtop use; aliquoting the stock upon first thaw avoids repeated freeze-thaw cycling of the antibody. Cross-reactivity across the three listed species reflects evolutionary conservation of TFIID subunits, so individual experiments should include species-matched secondary antibodies plus appropriate isotype controls. The 100 µl pack size supports dozens of immunoblots or stained tissue sections for transcription-factor research programs that profile multiple sample sets.
