Overexpression of CDK1 protein stained by CAB003799 and HPA003387 antibodies in thyroid cancer (THCA) from the Human Protein Atlas (THPA). (A) The expression pattern of CDK1 stained by the antibody CAB003799 in multiple cancers. Negative staining of CDK1 in non-cancerous thyroid epithelium (B: ×40, C: ×400). Weak positive staining of CDK1 in THCA tissues (D: ×40, E: ×400). (F) The expression pattern of CDK1 stained by the antibody HPA003387 in multiple cancers. Negative staining of CDK1 in non-cancerous thyroid epithelium (G: ×40, H: ×400). Strong positive staining of CDK1 in THCA tissues (I: ×40, J: ×400). Immunohistochemistry, 3,3’-Diaminobenzidine (DAB) staining.
