For example, TCR-like antibodies have been conjugated with fluorescent reagents to detect the expression level of the Wilms tumor 1 (WT1) RMFPNAPYL peptide/human leukocyte antigen (HLA)-A2 complex on the leukemia cell surface, which offers a clear map of the tumor-specific antigen profile [15]. The gene discussed is WT1; the disease is neoplasm.
