Twenty human keratins are resolved with two-dimensional gel electrophoresis into acidic (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).
Formulation
Prediluted in 1X PBS with 0.1 mg/ml BSA (US sourced) and 0.05% sodium azide; *For IHC use only*
Host
Mouse
Immunogen Region
Solubilized cytokeratin extract from human stratum coeum was used as the immunogen.
Isotype
Mouse IgG1, kappa
Species Reactivity
Human, Mouse, Rat
Note
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.
Format
Purified
Purity
Protein G purified
Storage
Store the Basic Cytokeratin antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).
Applications
IHC-P
