Cathepsin D Monoclonal Antibody (EM1901-02)

Applications

  • WB

  • IHC-P

REACTIVITY

  • Human

Western blot analysis of Cathepsin D on MCF-7 cell lysate. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in PBS for 1 hour at room temperature. The primary antibody was used at a 1:50,000 dilution in 5% BSA at room temperature for 2 hours. Goat Anti-Mouse IgG - HRP Secondary Antibody (HA1006) at 1:5,000 dilution was used for 1 hour at room temperature.

  • Immunohistochemical analysis of paraffin-embedded human liver tissue using anti-Cathepsin D antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 8.0-8.4) for 20 minutes.The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH2O and PBS, and then probed with the antibody (EM1901-02) at 1/200 dilution, for 30 minutes at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. Counter stained with hematoxylin and mounted with DPX.

SEQUENCE SIMILARITIES

Belongs to the peptidase A1 family.

TISSUE SPECIFICITY

Expressed in the aorta extracellular space (at protein level). Expressed in liver (at protein level).

POST-TRANSLATIONAL MODIFICATION

N- and O-glycosylated.; Undergoes proteolytic cleavage and activation by ADAM30.; As well as the major heavy chain which starts at Leu-169, 2 minor forms starting at Gly-170 and Gly-171 have been identified. An additional form starting at Ala-168 has also been identified.

SUBCELLULAR LOCATION

Lysosome. Melanosome. Secreted, extracellular space. Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV. In aortic samples, detected as an extracellular protein loosely bound to the matrix.

FUNCTION

Acid protease active in intracellular protein breakdown. Plays a role in APP processing following cleavage and activation by ADAM30 which leads to APP degradation. Involved in the pathogenesis of several diseases such as breast cancer and possibly Alzheimer disease.
