The antibody-based targeted delivery of bioactive molecules to tumor vasculature is an attractive avenue to concentrate therapeutic agents at cancer sites, while sparing normal organs. L19, F8 and F16 are clinical-stage human monoclonal antibodies, which selectively recognize splice isoforms of fibronectin and tenascin-C in the modified extracellular matrix of neoplastic lesions. Here, we report the first comparative immunohistochemical analysis of L19, F8 and F16 in human Hodgkin and non-Hodgkin...
