Expression analysis of TEX101 in various human tissues. Immunohistochemistry was performed to examine 28 types of tissues using a rabbit polyclonal antibody against TEX101. These organs covered a wide range, including cardiac muscle, lung, kidney, spleen, liver, esophagus, stomach, small intestine, colon, pancreas, salivary gland, ovary, uterine cervix, endometrium, breast, testis, prostate, hypophysis, thyroid gland, parathyroid gland, adrenal gland, thymus gland, tonsil, larynx, cerebellum, eye, peripheral nerves, and skin. The tissues sections were visualized using diaminobenzidine, and images were captured with a Leica DM2500 microscope (200×). Clear and strong staining was observed in the testis samples, but not in the other tissue samples, including ovary.
