From: Prognostic significance of cytoplasmic S100A2 overexpression in oral cancer patients
Immunohistochemical analysis of S100A2 in oral tissues. Paraffin-embedded sections of histologically normal mucosa and OSCC were stained using a rabbit monoclonal anti-S100A2 antibody (0.5 μg/ml, [EPR5392] (ab109494, Abcam, CA) as described in Material & Methods section. Panel represents (a) normal oral mucosa showing nuclear S100A2 immunostaining; (b) OSCC section illustrating cytoplasmic S100A2 and loss of nuclear staining in tumor cells; (c) Cervical cancer tissue section showing cytoplasmic S100A2 immunostaining; (d) OSCC section used as a negative control, showing no S100A2 immunostaining in tumor cells; (original magnification x 200).
