MYCN copy numbers determined using ddPCR in gDNA (Figure 4, Table 1) confirmed the gain in LAN-6 and normal diploid status in the SK-N-AS, SH-EP, SK-N-FI, NBL-S and CLB-GA neuroblastoma cell lines, which are reported in the literature (Table 1). The gene discussed is MYCN; the disease is neuroblastoma.
