Scientific Data Images for Mouse/Rat Cathepsin L Antibody

Detection of Mouse and Rat Cathepsin L antibody by Western Blot.

Detection of Mouse and Rat Cathepsin L by Western Blot.

Western blot shows lysates of rat liver tissue, mouse liver tissue (wild type), and mouse liver tissue (knock out). PVDF membrane was probed with 1 µg/mL of Goat Anti-Mouse Cathepsin L Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1515) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (HAF017). Specific bands were detected for Cathepsin L at approximately 22-38 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Cathepsin L antibody in Mouse Ovary by Immunohistochemistry (IHC-Fr).

Cathepsin L in Mouse Ovary.

Cathepsin L was detected in perfusion fixed frozen sections of mouse ovary using 15 µg/mL Goat Anti-Mouse Cathepsin L Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1515) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; CTS008) and counterstained with hematoxylin (blue).

Detection of Mouse Cathepsin L antibody by Simple WesternTM.

Detection of Mouse Cathepsin L by Simple WesternTM.

Simple Western lane view shows lysates of mouse liver tissue and HepG2 human hepatocellular carcinoma cell line, loaded at 0.2 mg/mL. Specific bands were detected for Cathepsin L at approximately 51 and 34 kDa (as indicated) using 10 µg/mL of Goat Anti-Mouse Cathepsin L Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1515) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: Cathepsin L

Cathepsin L is a lysosomal cysteine protease expressed in most eukaryotic cells. Cathepsin L is known to hydrolyze a number of proteins, including the proform of urokinase-type plasminogen activator, which is activated by Cathepsin L cleavage (1). Cathepsin L has also been shown to proteolytically inactivate alpha1-antitrypsin and secretory leucoprotease inhibitor, two major protease inhibitors of the respiratory tract (2). These observations, combined with the demonstration of increased Cathepsin L activity in the epithelial lining fluid of the lungs of emphysema patients, have led to the suggestion that the enzyme may be involved in the progression of this disease. Cathepsin L has also been identified as a major excreted protein of transformed fibroblasts, indicating the enzyme could be involved in malignant tumor growth (3). In Cathepsin L-deficient mice, it appears to play a critical role in cardiac morphology and function, epidermal homeostasis, regulation of the hair cycle, and MHC class II-mediated antigen presentation in cortical epithelial cells of the thymus (4, 5). Mouse Cathepsin L is synthesized as a 334 amino acid precursor with a signal peptide (residues 1-17), a pro region (residues 18-113), and a mature chain (residues 114-334).
