Since the complete open reading frame (ORF) of PTPRZ1 is large (~7kbp), we generated a well-characterized HLA-A*02+ glioblastoma cell line (U87) stably expressing a tandem minigene (TMG) encoding several antigens derived from the GAPVAC-101 and IMA950 trials, including the PTPRZ1 antigens of interest (Supplementary Fig. 4a, b, Supplementary Table 1)23,45. The gene discussed is PTPRZ1; the disease is glioblastoma.
