Fig. 1: Target antigen of FK002 is overexpressed in various human tumors.

A Schematic for constructing a cell surface mAb-target atlas for profiling live cells using PETAL. B–F IHC of human tumor tissues was used to evaluate FK002 expression in various human tumors or corresponding normal organs. Scale bar, 50 μm. The quantification data is shown in right below. Quantitative data are presented as means ± SD of n = 30,15,77 or 6 samples. ns not significant; *p < 0.05, ***p < 0.001.
