ALK-1 Protein Tumor Analysis - Immunohistochemistry (IHC) for ALK-1 Protein

A qualitative immunohistochemical (IHC) assay using a monoclonal antibody (usually Clone D5F3 or ALK1) against anaplastic lymphoma kinase (ALK) on tissue slides. It aims to detect aberrant ALK protein expression resulting from gene rearrangements or amplification, and is a therapeutic biomarker in several tumors.
