General description

Cathepsin D is synthesized as a 54kDa precursor which is proteolytically processed to an intermediate 48kDa single chain which matures into more stable 34kDa and 14kDa two chain form. It is an estrogen-regulated lysosomal protease that has been suggested to facilitate cancer cell migration and invasion by digesting the basement membrane, extracellular matrix, and connective tissue. Because of its mitogenic and proteolytic activities, it has been implicated as a prognostic marker in many tumor types, especially breast cancer. Cathepsin D is expressed in epithelial cells as well as in macrophages. Immunoreactivity of cancer cells and tissue infiltrating macrophages must be recorded separately.


84% sequence homology to mouse and rat.
This antibody recognizes Cathepsin D.


Epitope: Heavy Chain
GST-tagged recombinant protein corresponding to human Cathepsin D at the heavy chain.


Anti-Cathepsin D Antibody is an antibody against Cathepsin D for use in WB & IC.
Immunocytochemistry Analysis: 1:500 dilution from a previous lot detected Cathepsin D in A431 and HeLa cell lystes.
Research Category
Apoptosis & Cancer

Research Sub Category
Apoptosis - Additional


Evaluated by Western Blot in A431 cell lysate.

Western Blot Analysis: 1 µg/mL of this antibody detected Cathepsin D on 10 µg of A431 cell lysate.
