Background
Cytokeratins are proteins of cytoskeletal intermediate filaments, and their main function is to enable cells to withstand mechanical stress. In humans, 20 different cytokeratin isotypes have been identified. Cytokeratins 8, 18, 19, and 20 have been associated with bladder. Cytokeratin 18 (KRT18, also called K18), found in epithelial cells, is released from hepatocytes upon death.

Immunohistochemistry
IHC shows positive staining in paraffin-embedded human breast cancer. Anti-Keratin 18 antibody was used at 1/2000 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded human colon cancer. Anti-Keratin 18 antibody was used at 1/2000 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded human pancreatic carcinoma. Anti-Keratin 18 antibody was used at 1/2000 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
IHC shows positive staining in paraffin-embedded human prostatic hyperplasia. Anti-Keratin 18 antibody was used at 1/2000 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
Negative control: IHC shows negative staining in paraffin-embedded human cervical carcinoma. Anti-Keratin 18 antibody was used at 1/2000 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
Negative control: IHC shows negative staining in paraffin-embedded human lung squamous cell carcinoma. Anti-Keratin 18 antibody was used at 1/2000 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
Immunocytochemistry
ICC shows positive staining in MCF7 cells. Anti-Keratin 18 antibody was used at 1/25 dilution (Green) and incubated overnight at 4°C. Goat polyclonal Antibody to Rabbit IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. The cells were fixed with 100% ice-cold methanol and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue).Counterstain with tubulin (Red).
