    See all Cytokeratin 19 primary antibodies
  • Description
    Rabbit polyclonal to Cytokeratin 19
  • SpecificityIn our WB testing this antibody did not recognize mouse Cytokeratin 19, but customers have reported the antibody recognizes the protein in IHC-P with mouse tissue. Thus, we have removed mouse as a "does not react with" species and welcome further feedback from other researchers using this antibody in mouse.

Application Abreviews Notes
WB 1/20000. Detects a band of approximately 40 kDa (predicted molecular weight: 44 kDa).
IP 1/50.
IHC-P Use at an assay dependent concentration.
ICC/IF 1/250 - 1/500.
  • Application notesIs unsuitable for Flow Cyt.
  • Target

    • FunctionInvolved in the organization of myofibers. Together with KRT8, helps to link the contractile apparatus to dystrophin at the costameres of striated muscle.
    • Tissue specificityExpressed in a defined zone of basal keratinocytes in the deep outer root sheath of hair follicles. Also observed in sweat gland and mammary gland ductal and secretory cells, bile ducts, gastrointestinal tract, bladder urothelium, oral epithelia, esophagus, ectocervical epithelium (at protein level). Expressed in epidermal basal cells, in nipple epidermis and a defined region of the hair follicle. Also seen in a subset of vascular wall cells in both the veins and artery of human umbilical cord, and in umbilical cord vascular smooth muscle. Observed in muscle fibers accumulating in the costameres of myoplasm at the sarcolemma in structures that contain dystrophin and spectrin.
    • Sequence similaritiesBelongs to the intermediate filament family.
    • Developmental stagePresent in hair follicles at all stages of development.
    • DomainThis keratin differs from all other IF proteins in lacking the C-terminal tail domain.
