TCR expression constructs were generated as previously described (21 (link)). HLA-C*07:01, HLA-C*07:02 cDNA, as well as truncated CSPG4 cDNA ending with codon 562 were cloned into pcDNA3.1/V5-His TOPO (Invitrogen, Waltham, MA, USA) using standard cloning techniques as previously described (22 (link)). Plasmids were propagated in 10-beta competent E. coli (NEB, Ipswich, MA, USA) and were purified using the Midi or Maxi Plasmid Prep kits from Qiagen (Hilden, Germany).
