Immunohistochemistry staining for RGS17 protein with RGS17 antibody in the cancerous and normal tissues. (A) Validation of breast cancer tissues by Hematoxylin-Eosin (HE) stain. (B, C, D, E) Representative results of negative staining (-, B), weakly positive staining (+, C), moderate staining (++, D) and strong staining (+++, E) of RGS17 protein in breast cancer tissues are shown respectively. (F) HE staining of normal tissues. (G, H) Representative results of the negative staining (G) and weakly positive staining (H) of RGS17 protein in normal tissues. (I) Distributions of RGS17 staining grades (-, +, ++ and +++) in both normal tissues (I (a)) and breast cancer tissues (I (b)). Bar=100um.
