HLA-A and neoplasm: Although these cells were genetically engineered to express the restricting HLA class I allele, HLA-A*03:01 and HLA-A*11:01 cell surface levels were noted to be within the range of expression comparable to other non-engineered HLA-A*03:01+ and HLA-A*11:01+ mKRAS tumor cells lines (Supplementary Fig. 12a, b).
