Product Information

Intended Use:
In Vitro Diagnostic (IVD). Use in immunohistochemistry (IHC) test methods only.

The monoclonal antibody 1E8 is used for the in vitro examination of human biological samples using immunohistochemistry (IHC) methods for the qualitative identification of Cytokeratin 8. The clinical interpretation of any staining or its absence should be complemented by morphological studies and proper controls and should be evaluated within the context of the patient's clinical history and other diagnostic tests by a qualified pathologist.

Human, Mouse, Dog, Primate
Antibody 1E8 was raised against the 12 carboxy-terminal amino acids of HK-8 preceded by a cysteine, CKLVSESSDVLPK.
Phosphate-buffered solution + 0.03% Thimerosal.
The antibody was purified by affinity chromatography.
1.0 mg/ml
Storage & Handling
