Using patient matched FFPE tumor sections and peripheral blood mononuclear cell (PBMC) slides, we applied our panel of melanocytic (MITF, TYR, MLANA, GP100, and HTR2B) and immune antibodies (CD45, CD25, CD203c) as described in Fig. 1 to identify hybrid cell populations in addition to antibodies for TMSB10, CD74 and GPX1. The gene discussed is ENPP3; the disease is neoplasm.
