ED-B FN expression is abundant in biopsies of hematologic malignancies. ED-B FN expression of paraffin-embedded specimens of normal lymph node (A; magnification: ×100, left inset: ×20), and lymph node biopsies of diffuse large B-cell lymphoma (B; ×250, inset ×20); follicular lymphoma grade 2 (C; ×20, inset ×100), and classic Hodgkin lymphoma of mixed cellularity subtype (D; ×150). ED-B FN expression of bone marrow biopsies of normal bone marrow (E; ×50, inset ×200), multiple myeloma (F; ×100), unspecified peripheral T-cell lymphoma (G; ×200), and chronic myelogenous leukemia (H; ×200). All ED-B FN stainings were performed with the MX1 antibody.
