KRT13抗体

The keratin 13 (KRT13) antibody is a tool used to detect KRT13. a type I acidic keratin protein primarily expressed in non-cornified stratified epithelial tissues, such as those in the oral mucosa, esophagus, and cervix. KRT13 pairs with KRT4 to form intermediate filaments, contributing to epithelial structural integrity and cellular differentiation. Its expression is often downregulated in squamous cell carcinomas (SCCs), making it a potential diagnostic or prognostic marker for cancers like esophageal or oral SCC. KRT13 mutations are linked to hereditary mucosal disorders, such as white sponge nevus, characterized by thickened, white oral lesions. Researchers use KRT13 antibodies in techniques like immunohistochemistry (IHC) and immunofluorescence (IF) to study tissue-specific expression patterns, monitor disease progression, or explore epithelial cell differentiation mechanisms. Commercially available antibodies are typically validated for specificity, often targeting epitopes within the conserved helical domains of KRT13. Its role in maintaining epithelial homeostasis and association with pathologies continue to drive interest in both basic research and clinical applications.
