Scientific Data Images for Mouse Cathepsin D Antibody

Detection of Mouse Cathepsin D antibody by Western Blot.

Detection of Mouse Cathepsin D by Western Blot.

Western blot shows lysate of mouse intestine tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Mouse Cathepsin D Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1029) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (HAF017). Specific bands were detected for Cathepsin D at approximately 28 and 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Cathepsin D in RAW 264.7 Mouse Cell Line.

Cathepsin D was detected in immersion fixed RAW 264.7 mouse monocyte/macrophage cell line using Goat Anti-Mouse Cathepsin D Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1029) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; NL001) and counterstained with DAPI (blue). Specific staining was localized to lysosomes.

Cathepsin D antibody in Mouse Intestine by Immunohistochemistry (IHC-Fr).

Cathepsin D in Mouse Intestine.

Cathepsin D was detected in perfusion fixed frozen sections of mouse intestine using 15 µg/mL Goat Anti-Mouse Cathepsin D Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1029) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; CTS008) and counter-stained with hematoxylin (blue). Specific labeling was localized to epithelial cells in intestinal villi. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Background: Cathepsin D

Cathepsin D is a lysosomal aspartic protease of the pepsin family (4). Mouse Cathepsin D is synthesized as a precursor protein, consisting of a signal peptide (residues 1-20), a propeptide (residues 21-64), and a mature chain (residues 65-410) (1-3). It is expressed in most cells and over-expressed in breast cancer cells (5). It is a major enzyme in protein degradation in lysosomes, and also involved in the presentation of antigenic peptides. Mice deficient in this enzyme showed a progressive atrophy of the intestinal mucosa, a massive destruction of lymphoid organs, and a profound neuronal ceroid lipofucinosis, indicating that Cathepsin D is essential for proteolysis of proteins regulating cell growth and tissue homeostasis (6). Cathepsin D secreted from human prostate carcinoma cells is responsible for the generation of angiostatin, a potent endogeneous inhibitor of angiogenesis (6).
