CK8 Cytokeratin 35BH11
Use
Cytokeratin 8 (CK8) is an intermediate filament protein expressed in epithelial cells, particularly in the cytoskeleton of hepatocytes, pancreatic ductal cells, and other glandular tissues. In pathology, CK8 is used to identify epithelial cells and differentiate between carcinomas and other tumor types, especially in the liver, lung, and gastrointestinal tract.
Special Instructions
Fresh Tissues: Specimens may be fixed in formalin for 24-72 hours by collection sites, then transferred to 70% ethanol and stored at 2-8°C for longer term storage if needed. Samples must be tested 3 months after placing in ethanol. Unstained slides: Positively charged glass slides required to prevent background staining and prevent tissue loss. Slides should be left unbaked.
Limitations
Specimens must be fixed in 10% NBF or B plus. All other fixatives will be rejected. Stated turn-around-times (TATs) are for clinical use only and subject to change based on biopharma protocol requirements. Final TATs will be specified in the biopharma study contract.
