KRT5 Antibody AGD-11 recognizes keratin 5 (KRT5), a type II intermediate filament protein expressed predominantly in the basal cells of stratified and pseudostratified epithelia. Also known as cytokeratin 5 or CK5, this approximately 58 kDa protein contributes to the mechanical stability of epithelial tissues by forming a cytoplasmic filament network. KRT5 is particularly abundant in basal keratinocytes of the epidermis and in basal epithelial populations of the prostate, mammary gland, and respiratory tract. Its expression is frequently used to identify basal epithelial compartments and investigate cellular differentiation.
KRT5 forms heterodimers with keratin 14 (KRT14), a type I intermediate filament protein that is expressed in many of the same epithelial cells. These complexes assemble into intermediate filaments that maintain cellular architecture and help epithelial cells resist mechanical stress. During epidermal differentiation, basal keratinocytes expressing KRT5 and KRT14 give rise to suprabasal cells that increasingly express keratins 1 and 10. Changes in these expression patterns provide information about epithelial maturation, tissue renewal, and responses to injury. KRT5 is therefore studied in developmental biology, epithelial stem cell research, and wound healing.
In tumor pathology, KRT5 is associated with squamous differentiation and basal-like epithelial phenotypes. It is frequently expressed in squamous cell carcinomas arising in the lung, cervix, and head and neck. KRT5 is commonly evaluated alongside KRT6 and p63 when investigating squamous differentiation. In breast cancer, KRT5 expression is associated with subsets of basal-like tumors, although additional markers are required for molecular classification. In prostate tissue, KRT5 staining identifies basal epithelial cells surrounding benign glands, while conventional prostatic adenocarcinoma typically lacks a basal cell layer. These distinctions make KRT5 useful for examining epithelial organization and tumor differentiation.
Pathogenic variants in KRT5 can cause epidermolysis bullosa simplex, an inherited disorder characterized by skin fragility and blister formation. KRT5 is also investigated in epithelial regeneration and tissue remodeling. NSJ Bioreagents offers rabbit monoclonal clone AGD-11, developed against a C-terminal region of human KRT5. The antibody provides an additional clone option for investigating KRT5 expression and complements other antibodies directed against different regions of the protein. A KRT5 Antibody AGD-11 supports research into basal epithelial differentiation, intermediate filament organization, and epithelial tumor biology.
Explore our protein microarray-validated Cytokeratin 5 Antibody KRT5/3594 for investigating basal epithelial differentiation, squamous cell carcinomas, and keratin filament organization.
Optimal dilution of the KRT5 Antibody AGD-11 / Cytokeratin 5 Rabbit Monoclonal Antibody should be determined by the researcher.
A synthetic peptide specific to the C-terminal region of human Cytokeratin 5 / KRT5 was used as the immunogen for the KRT5 antibody.
Store the KRT5 antibody at -20oC.
