Immunohistochemical detection of ubiquitin D (UBD) and cyclin-dependent kinase 4 inhibitor D (CDKN2D) expression in left-sided colon carcinoma (LSCC) and right-sided colon carcinoma (RSCC). Immunohistochemical analyses were performed to determine (A and B) CDKN2D and (C and D) UBD expression in (A and C) LSCC and (B and D) RSCC. Sections were stained using the avidin-biotin complex method. The coloration was developed with 3,3′-diaminobenzidine (DAB), and the sections were then counterstained with hematoxylin. Positive staining for either CDKN2D or UBD appeared brown. Magnification, x400.
