Immunohistochemical analysis of BEX4 expression in OSCC. In total, 30 paired tumor and normal tissues from patients with OSCC. a Specificity of BEX4 antibody. Western bot analysis showed that the anti-human BEX4 antibody can specifically detect the recombinant human BEX4 protein. b Distribution of tissue BEX4 expression level in our OSCC cohort. c Representative immunohistochemical staining images showing BEX4 expression on OSCC tissues and paired normal epithelia
