Cathepsin S is a lysosomal cysteine protease that plays a central role in antigen processing and presentation, particularly in professional antigen-presenting cells such as dendritic cells, macrophages, and B lymphocytes. This enzyme is essential for the degradation of the invariant chain associated with MHC class II molecules, making it a key regulator of adaptive immune responses. Beyond its immunological functions, Cathepsin S has garnered significant research interest for its involvement in extracellular matrix remodeling, with implications in atherosclerosis, tumor invasion, and inflammatory diseases.
This recombinant monoclonal antibody, generated from clone 9B10, offers the reproducibility and consistency that demanding experimental workflows require. Because recombinant antibodies are produced from defined sequences rather than traditional hybridoma methods, researchers benefit from lot-to-lot uniformity that supports reliable data across longitudinal studies and multi-site collaborations. The rabbit IgG format provides excellent signal-to-noise characteristics in immunodetection applications.
Validation studies demonstrate robust performance in immunohistochemistry on formalin-fixed, paraffin-embedded human tissues. Testing in human tonsil tissue reveals the expected expression pattern in lymphoid compartments where antigen-presenting cells are abundant, while staining in human kidney tissue confirms detection in this metabolically active organ. For IHC applications, dilutions ranging from 1:50 to 1:200 provide flexibility for optimization across different tissue types and detection systems, with validated protocols utilizing citrate buffer antigen retrieval at pH 6.0.
This antibody serves researchers investigating immune cell biology, antigen presentation pathways, and the broader roles of cysteine proteases in tissue remodeling and disease pathogenesis.
