1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
1/100 - 1/250.
Together with KRT19, helps to link the contractile apparatus to dystrophin at the costameres of striated muscle.
Observed in muscle fibers accumulating in the costameres of myoplasm at the sarcolemma membrane in structures that contain dystrophin and spectrin. Expressed in gingival mucosa and hard palate of the oral cavity.
Belongs to the intermediate filament family.
Phosphorylation on serine residues is enhanced during EGF stimulation and mitosis. Ser-74 phosphorylation plays an important role in keratin filament reorganization. O-glycosylated. O-GlcNAcylation at multiple sites increases solubility, and decreases stability by inducing proteasomal degradation. O-glycosylated (O-GlcNAcylated), in a cell cycle-dependent manner.
