Fig. 5: IgG secreted by tumor cells.
From: Cancer cell-derived immunoglobulin G activates platelets by binding to platelet FcγRIIa
IgG was analyzed by ELISA (a) and human Ig isotype array (b). Data are represented as the mean ± SEM for three independent experiments. ##P < 0.01 and ***, ###P < 0.001 compared with the culture medium group. c Expression of cancer cell-derived IgG was analyzed by RP215 antibody. Liver cell HL-7702 was used as a negative control. d Cancer cell-derived IgG expression in SMMC.7721, EJ and SiHa cells were analyzed by immunofluorescence, and five randomly selected fields were examined. Scale bar: 100 μm
