D2-40 by Immunohistochemistry
Also known as: D240 IHC
Use
Immunohistochemical stain utilizing the monoclonal antibody D2-40 (podoplanin) to identify lymphatic endothelial differentiation, commonly applied to evaluate vascular tumors such as lymphangiomas, Kaposi sarcoma, subsets of angiosarcoma, and mesothelial differentiation. Helps distinguish lymphatic origin from blood vascular origin in formalin-fixed paraffin-embedded tissue specimens.
