Twenty human keratins are resolved with two-dimensional gel electrophoresis into acidic (pI <5.7) and basic (pI >6.0) subfamilies. This antibody recognizes basic (Type II or HMW) cytokeratins, which include 67kDa (CK1); 64kDa (CK3); 59kDa (CK4); 58kDa (CK5); 56kDa (CK6); 52kDa (CK8). Many studies have shown the usefulness of keratin markers in cancer research and tumor diagnosis. The basic family clone AE3 is commonly used in combination with clone AE1 as a pan cytokeratin antibody acidic + basic cocktail (Cat No V2330).

Application Notes

Differences in protocols and secondaries may cause the Basic Cytokeratin antibody to need titering for optimal performance.

1. FFPE staining requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.
2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.


Solubilized cytokeratin extract from human stratum corneum was used as the immunogen.


Store the Basic Cytokeratin antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
