Immunohistochemistry analysis of formalin fixed, paraffin embedded sections of human liver tissue labeling Cytokeratin 7 with ab9021 at 1/100; showing positive staining in the epithelial cells lining the bile ducts and no reactivity in hepatocytes or connective tissue.

ab9021 staining normal pig skin tissue section (frozen), staining epithelial cells using ab9021 at 1/500.

Immunofluorescent staining of β-galactosideasae and cytokeratin expression of urinary bladder after intravesical treatment with Adeno-Cre

Formalin-fixed, paraffin-embedded mouse bladder tissue stained for β-galactosidase (green, A) or Cytokeratin 7 (red, B). Panel C shows the colocalization of β-galactosidase and Cytokeratin 7. The nuclear counterstain is DAPI (blue).

Cytokeratin 7 was detected using ab9021.
