Immunohistochemical detection of S100As expression in pancreatic cancer. IHC was performed to test S100As protein level in pancreatic cancer tissues (n = 43) and their counterparts (n = 28). The intensity was scored as “zero,” “one,” “two,” and “three”; that was negative, weak, moderate, and strong staining, respectively. The positively stained cells percentage was scored as “0 to 100%” The final IHC score was obtained by product between intensity score and stained area. *P < 0.05, **P < 0.01, ns, not significant
