GYPC and adrenal cortex carcinoma: For immunization of mice, we used the recombinantly expressed NSDV GP38-his-FLAG and obtained a potent mAb (6F6 A3B) that was shown to specifically detect NSDV GPC in indirect immunofluorescence assay (iIFA; Fig. S2) as well as GPC cleavage products in immunoblot of NSDV-infected human adrenocortical carcinoma cells, also known as SW13 cells (Fig. 3A).
