Data Examples
Immunohistochemistry
Cathepsin S in Human Lymph Node. Cathepsin S was detected in immersion fixed paraffin-embedded sections of human lymph node using Goat Anti-Human Cathepsin S Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF1183) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in lymphocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Cathepsin S

Cathepsin S is a lysosomal cysteine protease of the papain family (1). It plays a major role in the processing of the MHC class II-associated invariant chain (2). It has been implicated in the pathogenesis of several diseases such as Alzheimer’s disease and degenerative disorders associated with the cells of the mononuclear phagocytic system (1). Human Cathepsin S is synthesized as a preproenzyme of 331 amino acid residues consisting a signal peptide (residues 1‑16), a pro region (residues 17‑114), and the mature enzyme (residues 115‑331) (3‑5). Cathepsin S is less abundant in tissues than Cathepsins B, L and H. The highest levels have been found in lymph nodes, spleen, macrophages and other phagocytic cells.
