Of these candidates, we selected eight mAbs (PODOC1 through PODOC8) with favorable selectivity profiles based on flow cytometry screening of tumor cell lines known to highly express podocalyxin (MDA-MB-231, CAOV-3, A-172), tumor cell lines known to express low levels of podocalyxin (MCF7, T47D, OVCAR-10) and non-tumor-derived human cells known to express podocalyxin (human umbilical vascular endothelial cells and HEK293 cells) (Table 1). This evidence concerns the gene PODXL and neoplasm.
