CTSK Antibody (Center R222)

Purified Rabbit Polyclonal Antibody (Pab)

  • IHC-P - CTSK Antibody (Center R222) AP7381c
    Formalin-fixed and paraffin-embedded human breast carcinoma with CTSK Antibody (Center R222), 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 - CTSK Antibody (Center R222) AP7381c
    Flow cytometric analysis of ZR-75-1 cells using CTSK Antibody (Center R222)(bottom histogram) compared to a negative control cell (top histogram). FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.
  • WB - CTSK Antibody (Center R222) AP7381c
    Western blot analysis of CTSK (arrow) using rabbit polyclonal CTSK Antibody (Center R222) (Cat.#AP7381c). 293 cell lysates (2 ug/lane) either nontransfected (Lane 1) or transiently transfected with the CTSK gene (Lane 2) .

The protein encoded by this gene is a lysosomal cysteine proteinase involved in bone remodeling and resorption. This protein, which is a member of the peptidase C1 protein family, is predominantly expressed in osteoclasts. However, the encoded protein is also expressed in a significant fraction of human breast cancers, where it could contribute to tumor invasiveness. Mutations in this gene are the cause of pycnodysostosis, an autosomal recessive disease characterized by osteosclerosis and short stature. This gene may be subject to RNA editing.
