From: Detection of ALK protein expression in lung squamous cell carcinomas by immunohistochemistry
Lung SqCC samples were diagnosed combining morphologic appearance and IHC staining including thyroid transcription factor-1 (TTF-1), transformation-related protein 63 (p63) and/or cytokeratin (CK5/6). A: Hematoxlin and eosin staining. B: IHC staining for p63. C: IHC staining for CK5/6. D: IHC staining for TTF-1. Original magnification, ×400.
