Product Details
Background
Thyroid transcription factor-1 (synonymes: Homeobox protein Nkx-2.1) is a 371 amino acid protein, 39 KDa, which belongs to the NKX homeobox transcription factor family. TTF-1 stimulate or repress transcription of particular genes by binding to their regulatory sequences. TTF-1 plays a role in regulating genes in the thyroid, lung and brain. Its molecular targets in the thyroid gland are thyroglobulin, thyroperoxidase and thyrotropin receptor. TTF-1 activates transcription of the genes encoding these proteins. In lung, TTF-1 promotes the transcription of the surfactant proteins A to D, and the Clara cell secretory protein. In brain, the molecular targets of TTF-1 are unknown. Besides being a tissue-specific transcription promoter in adult organs, TTF-1 has been suggested a role in morphogenesis and cytodifferentiation. Among thyroid neoplasms, TTF1 is seen in virtually all tumours of follicular derivation. In diagnostic pathology, TTF-1 is useful as marker for pulmonary adenocarcinoma and pulmonary neuroendocrine malignancy, including small cell lung carcinoma. It can be used to differentiate primary lung adenocarcinoma from metastasis of extrapulmonary origin.
Application
To ensure optimal assay performance, AREX recommends conducting reagent titration tailored to each testing system for optimal detection results.
*Results are sample-specific. Please refer to your local assay conditions and test parameters for reference.

FAQs
Are the pathology antibodies provided by AREX raw antibodies or ready-to-use solutions?
AREX Biosciences specializes in supplying high-quality IHC pathology raw antibodies (Raw Antibodies). We do not manufacture ready-to-use working solutions or IVD diagnostic reagents. We mainly provide concentrated raw materials to pathology reagent manufacturers and diagnostic platform companies to support product development and OEM production.
What development scenarios are pathology raw antibodies mainly used for?
Our raw antibodies are primarily used for the research, performance optimization, validation, and commercial-scale production of pathology IHC detection reagents. They are also suitable for companion diagnostics (CDx) projects and antibody screening.
How can I evaluate whether a raw antibody is suitable for our staining platform?
It is recommended to focus on specificity, sensitivity, background control, and performance on your target automated platforms (such as Roche Ventana, Leica Bond, Agilent Dako, etc.). We can provide internal test data for reference, but we recommend partners perform actual validation on their own platforms.
Can you provide samples for platform validation?
Yes. We can provide validation samples depending on the specific product. Some products may be provided free of charge, while others may involve a small sample fee. Handling fee and shipping fee will be charged separately. Please contact us for detailed confirmation.
How should raw antibodies be paired with detection systems?
AREX raw antibodies can be used with various polymer detection systems and ancillary reagents. We recommend optimization in combination with the ARExVisual® system or your existing detection platform to achieve better signal intensity and background control.
