Detection of Recombinant Human and Mouse Cathepsin L by Western Blot. Western blot shows 100 ng of Recombinant Human Cathepsin L (Catalog # 952-CY), Recombinant Mouse Cathepsin L (Catalog # 1515-CY), Recombinant Human Cathepsin V (Catalog # 1080-CY), Recombinant Human Cathepsin K, Recombinant Human Cathepsin S (Catalog # 1183-CY), Recombinant Human Cathepsin H (Catalog # 7516-CY), and Recombinant Human Cathepsin F. PVDF Membrane was probed with 1 µg/mL of Rat Anti-Human/Mouse Cathepsin L Monoclonal Antibody (Catalog # MAB9521) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for Cathepsin L at approximately 35 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3. For natural samples, we recommend the use of Catalog # AF1515.

Cathepsin L in Human Kidney. Cathepsin L was detected in immersion fixed paraffin-embedded sections of human kidney using Rat Anti-Human/Mouse Cathepsin L Monoclonal Antibody (Catalog # MAB9521) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Rat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS017) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in tubular epithelial cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Cathepsin L in Mouse Kidney. Cathepsin L was detected in immersion fixed frozen sections of mouse kidney using Rat Anti-Human/Mouse Cathepsin L Monoclonal Antibody (Catalog # MAB9521) at 8 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Rat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS017) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in tubular epithelial cells. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

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 alpha 1-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).
