Anti-TTF1 Antibody

TTF1 (Thyroid Transcription Factor 1, also known as NKX2-1) is a 42 kDa homeodomain-containing transcription factor critical for thyroid follicular cell differentiation, lung alveolar development, and forebrain patterning. This unconjugated rabbit polyclonal antibody from Antibodies.com is supplied in a 100 µl vial at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.3, and is validated for western blot (WB) workflows with reactivity confirmed against human, mouse, and rat samples. Investigators apply it to studies of lung adenocarcinoma lineage markers, thyroid carcinoma characterisation, and neuroendocrine tumour differentiation. To preserve activity, aliquot the reagent upon arrival to limit freeze-thaw cycles and store at -20°C; refrigerated storage at 4°C supports short-term use across several weeks. The polyclonal format provides recognition of multiple epitopes on TTF1, supporting reproducible detection of native and recombinant protein in immunoblotting protocols.
