ImmunoPET for assessing the differential uptake of a CD146-specific monoclonal antibody in lung cancer

Overexpression of CD146 in solid tumors has been linked to disease progression, invasion, and metastasis. We describe the generation of a 64Cu-labeled CD146-specific antibody and its use for quantitative immunoPET imaging of CD146 expression in six lung cancer models. The anti-CD146 antibody (YY146) was conjugated to 1,4,7-triazacyclononane-triacetic acid (NOTA) and radiolabeled with 64Cu. CD146 expression was evaluated in six human lung cancer...
