Cytokeratin 19 fragment (CYFRA 21-1) is a fragment of cytokeratin 19 that is typically associated with epithelial cell cancers, including NSCLC, and is typically associated with the SQLC type. Since cytokeratins are structural proteins of keratin-containing intermediate filaments found in the epithelial cells, their degradation produces soluble fragments which are measurable in the blood of lung cancer patients as a tumor marker. Other examples of cytokeratin fragments include tissue polypeptide antigen and tissue polypeptide-specific antigen. CYFRA 21-1 is known to be correlated with disease response and the prognosis of lung cancer but cannot be used to differentiate cancer patients from patients with respiratory diseases.

IHC shows positive staining in paraffin-embedded human colon cancer. Anti-Cytokeratin 19 fragment (CY211) antibody was used at 1/1000 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.

免疫细胞化学
ICC shows positive staining in MCF7 cells. Anti-Cytokeratin 19 fragment (CY211) antibody was used at 1/500 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).
