Use in combination with:

Detection Reagent: Human Cathepsin S Biotinylated Antibody (Catalog # BAF1183)

Standard: Recombinant Human Cathepsin S Protein, CF (Catalog # 1183-CY)

Measured by its ability to neutralize activation and the resulting activity of Recombinant Human Cathepsin S (0.25 µg/mL, Catalog # 1183-CY) in cleaving the fluorogenic peptide substrate Mca-RPKPVE-Nval-WRK(Dnp)-NH2 (10 µM, Catalog # ES002). The Neutralization Dose (ND50) is typically 0.2-1.8 µg/mL.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

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 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1183) 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).

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.
