Research context & evidence
Target information is kept separate from product-level validation so you can review the biology and the reagent evidence independently.
Keratin 18 (KRT18/CK-18) is a type I intermediate-filament protein expressed prominently in simple epithelial cells. It forms heteropolymeric filaments, notably with keratin 8, that contribute to cytoskeletal organisation, mechanical stability and epithelial-cell resilience.
KRT18 is studied in epithelial-cell biology, intermediate-filament organisation, cytoskeletal integrity and cellular stress responses. Review the linked ABMIUM research products and confirm species, sample type, application, assay format and product-level validation before use.
