Immunohistochemistry of hu3F8 scFv variants on different tumor samples

The strength is defined as follows: negative (−); weak, heterogeneous membrane staining (+); weak, homogeneous membrane staining (++); strong, heterogeneous membrane staining (+++); strong, homogeneous membrane staining (++++).

^a NB, neuroblastoma; OS, osteosarcoma; RMS, rhabdomyosarcoma; Ewings, Ewing sarcoma; DSRCT, desmoplastic small round cell tumor.

^b scFv concentration is 3 μg/ml; blank values indicate no data collected.
