Fig. 2From: Effective adoptive immunotherapy of triple-negative breast cancer by folate receptor-alpha redirected CAR T cells is influenced by surface antigen expression levelFRα may represent a new therapeutic target in TNBC. FRα surface expression in TNBC cell lines was measured by flow cytometry. FRα-specific mAb MOv18 was used to measure FRα expression on various ovarian cancer (OC) and breast cancer (BC) cell lines (open empty histogram), compared to a matched isotype antibody control (filled gray histogram)Back to article page
