isolation of neo-antigen specific TCR genes from tumor biopsies that are routinely obtained from cancer patients during treatment. The tumor-infiltrating lymphocytes (TIL) obtained by these tumor biopsies frequently express TCRs specific for mutated proteins found in cancer cells (neo-antigens). The company’s proprietary technology uses state-of-the-art DNA sequencing, DNA synthesis and genetic screening tools to identify such neo-antigen specific T cell receptor genes within tumor biopsies with high sensitivity, specificity and at scale.
