TTF-1 Antibody (Immunohistochemistry)

The TTF-1 (Thyroid Transcription Factor-1) Antibody is a crucial IHC marker.
It helps identify tumors that originate from the lung and thyroid.
In addition, TTF-1 is a 38 kDa nuclear transcription factor expressed in type II pneumocytes, Clara cells,
and thyroid follicular epithelial cells.

Moreover, TTF-1 shows strong nuclear positivity in lung adenocarcinomas and thyroid carcinomas.
As a result, it becomes essential for distinguishing primary lung tumors from
metastatic carcinomas. Therefore, TTF-1 plays a major role in diagnostic pathology.

🔬 Features and Benefits

• Specific marker for pulmonary and thyroid-origin tumors
• Clear brown nuclear staining in positive cells
• Helps differentiate primary lung carcinoma from metastasis
• Compatible with standard IHC laboratory protocols
• Stable for up to 18 months at 2–8 °C

💡 Diagnostic Applications

• Detection of lung adenocarcinoma and small-cell lung carcinoma
• Identification of papillary and follicular thyroid carcinomas
• Distinguishing primary lung carcinoma from secondary metastatic tumors
• Research involving tissue-specific gene expression
