We validated a selection of genes from RNAseq using RT-PCR (Figure 2—figure supplement 2), as well as transient co-injection of linearized transgene with our EPS mix to assess tumor cell-specific expression of lymphoid rag2:EGFP and myeloid mpeg1.1:EGFP at 30 dpf (Figure 2F–I). The gene discussed is RAG2; the disease is neoplasm.
