Flow cytometry testing of permeabilized human HeLa cells with Cytokeratin 4 antibody (clone KRT4/2804); Red=isotype control, Blue= Cytokeratin 4 antibody.
4 / 4
Analysis of HuProt(TM) microarray containing more than 19,000 full-length human proteins using Cytokeratin 4 antibody (clone KRT4/2804). These results demonstrate the foremost specificity of the KRT4/2804 mAb. Z- and S- score: The Z-score represents the strength of a signal that an antibody (in combination with a fluorescently-tagged anti-IgG secondary Ab) produces when binding to a particular protein on the HuProt(TM) array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If the targets on the HuProt(TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-scores. The S-score therefore represents the relative target specificity of an Ab to its intended target.

Further Information

Application Details :
Flow cytometry: 1-2ug/million cells in 0.1ml,Immunofluorescence: 1-2ug/ml,Immunohistochemistry (FFPE): 1-2ug/ml
Application Note:
Optimal dilution of the antibody should be determined by the researcher.
Description:
Cytokeratin 4 (KRT4) is an intermediate filament protein associated with Cytokeratin 13 (KRT13). It is expressed in suprabasal cells of non-keratinized stratified squamous epithelium of esophagus, cornea, anus, larynx, pharynx and tongue. Decreased expression of KRT4 is associated with head and neck squamous carcinoma. It is helpful in differentiation of squamous cell carcinoma of esophagus origin from that of thyroid origin.
