KRT4 Antibody (C-term)

Purified Rabbit Polyclonal Antibody (Pab)

  • WB - KRT4 Antibody (C-term) AP6724b
    Western blot analysis of KRT4 antibody (C-term) (Cat. #AP6724b) in mouse spleen tissue lysates (35ug/lane). KRT4 (arrow) was detected using the purified Pab.
  • IHC-P - KRT4 Antibody (C-term) AP6724b
    Formalin-fixed and paraffin-embedded human prostate carcinoma reacted with KRT4 Antibody (C-term), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.
  • FC - KRT4 Antibody (C-term) AP6724b
    Flow cytometric analysis of MDA-231 cells using KRT4 Antibody (C-term)(bottom histogram) compared to a negative control cell (top histogram). FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.

The protein is a member of the keratin family. The type II cytokeratins consist of basic or neutral proteins which are arranged in pairs of heterotypic keratin chains coexpressed during differentiation of simple and stratified epithelial tissues. This type II cytokeratin is specifically expressed in differentiated layers of the mucosal and esophageal epithelia with family member KRT13.
