Intended use research use only
Tested species reactivity see individual antibody datasheet


Tested applications Tested dilutions
Immunohistochemistry (IHC) - frozen anti-Keratin K8/K18: 1:100
Immunohistochemistry (IHC) - paraffin anti-Keratin K8/K18: 1:50 – 1:100 (microwave treatment recommended)
Western Blot (WB) anti-Keratin K8/K18: 1:1,500 – 1:2,500; anti-guinea pig HRP: 1:2,500 - 1:100,000



anti-Keratin K8/K18 antibody:
Reactive polypeptide (specificity): Mr 52 500 and 45 500; Keratins K8 and K18 (formerly also designated cytokeratins 8 and 18) of simple type epithelium.
Tumors Specifically Detected: All adenocarcinoma tested, undifferentiated carcinoma, hepatocellular carcinoma, cervix carcinoma

anti-guinea pig IgG goat polyclonal, HRP conjugate:
Whole Guinea Pig IgG secondary antibodies are isolated from antisera by immunoaffinity chromatography. The antibody is conjugated to Horseradish peroxidase (HRP) and is commonly used for WB, IHC and ELISA.
Based on immunoelectrophoresis and/or ELISA, the antibody reacts with whole molecule guinea pig IgG. It also reacts with the light chains of other guinea pig immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins. The antibody may cross-react with immunoglobulins from other species.
