Human Keratin 4 (KRT4) ELISA Kit

Cytokeratin 4 is a type II intermediate filament protein expressed in non-keratinized stratified squamous epithelia, including the oral mucosa, esophagus, and ocular surface. The Assay Genie Human Keratin 4 (KRT4) ELISA Kit provides a quantitative immunoassay for measuring this protein in human tissue homogenates and cell lysates, supporting research into epithelial differentiation, mucosal barrier biology, and KRT4 mutations associated with conditions such as white sponge nevus.

Each kit provides 96 assays per pack with reagents for standard curve generation and sample quantification. Researchers can pair the assay with western blot or immunohistochemistry workflows to validate KRT4 expression changes in disease models, treated cell cultures, or tissue specimens, and the human-specific reactivity supports work with patient-derived samples.
