Anti-TCEA1 Antibody

TCEA1 (Transcription Elongation Factor A1) is a key regulator of RNA polymerase II transcription elongation, facilitating the enzyme's ability to read through transcriptional blocks on DNA templates. This rabbit polyclonal antibody from Antibodies.com targets human TCEA1 and is supplied as a 200 µl aliquot of unconjugated IgG for use in Western blot and immunohistochemistry workflows.

Key specifications include a polyclonal rabbit host, IgG isotype, and an unconjugated format that allows pairing with HRP-, biotin-, or fluorophore-labelled secondary reagents. Reactivity is confirmed against human TCEA1, and the antibody has been validated for both WB and IHC applications.

Typical research applications include profiling the transcription elongation machinery in cancer cell lines, mapping elongation factor occupancy at active gene promoters, and characterising TCEA1 expression across normal versus tumour tissue microarrays by IHC. The unconjugated format also makes the reagent compatible with custom biotinylation or fluorescent labelling for multiplexed detection. Store refrigerated upon arrival; aliquot the antibody to limit freeze-thaw cycles and preserve long-term titre.
