SpecificityThe specificity of this antibody has been confirmed by WB and IHC against the antigen. Human; rat;
Species ReactivityHuman, Rat
Immunogen DescriptionThe antigen is a mixture of clones C-11, PCK-26, CY-90, KS-1A3, M20 and A53-B/A2. This antibody detects human Cytokeratins 1, 4, 5, 6, 8, 10, 13, 18 and 19.
Application DetailsImmunohistochemistry (IHC) and Western Blotting (WB). A concentration of 1.0-2.0 µg/mL is recommended for WB. Human Cytokeratin 1 has a predicted length of 644 amino acids and MW of 66 kDa. A concentration of 2.0-5.0 µg/mL is recommended to detect the protein in formalin fixed and paraffin embedded tissues as well as formalin/acetone fixed tissues. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Scientific BackgroundCytokeratins belong to the intermediate filament family of proteins and are classified according to their type. Type I Cytokeratins are low molecular weight and acidic whereas Type II Cytokeratins are higher weight and basic to neutral. This antibody broadly detects Cytokeratins 1, 4, 5, 6, 8, 10, 13, 18 and 19. Expression of these Cytokeratins is frequently tissue specific.
