These results were supported by reports from Amoury et al. (2016) and Bauerschlag et al. (2016) demonstrating the use of SNAP-tag conjugates for the detection of tumor sections in ovarian and breast cancer tumor biopsies (overexpressing CSPG4, EGFR, and EpCAM) using fluorescence immunohistochemistry and the induction of targeted killing with IC50 values of 45–90 μM and 62–165 μM, respectively (Table 2) [89]. The gene discussed is EGFR; the disease is neoplasm.
