ELISA: 1:1,000
Applications are based on unconjugated antibody.
Western Blot (WB)
(Western blot analysis of CTSS antibody (Center) in MDA-MB231 cell line lysates (35ug/lane). CTSS (arrow) was detected using the purified Pab.)
Immunohistochemistry (IHC)
(CTSS Antibody (Center) IHC analysis in formalin fixed and paraffin embedded human testis tissue followed by peroxidase conjugation of the secondary antibody and DAB staining. This data demonstrates the use of the CTSS Antibody (Center) for immunohistochemistry. Clinical relevance has not been evaluated.)
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene, a member of the peptidase C1 family, is a lysosomal cysteine proteinase that may participate in the degradation of antigenic proteins to peptides for presentation on MHC class II molecules. The encoded protein can function as an elastase over a broad pH range in alveolar macrophages. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.

Uniprot Description
CTSS: Thiol protease. Key protease responsible for the removal of the invariant chain from MHC class II molecules. The bond- specificity of this proteinase is in part similar to the specificities of cathepsin L and cathepsin N. Belongs to the peptidase C1 family. 2 isoforms of the human protein are produced by alternative splicing.
Protein type: Protease; EC 3.4.22.27
Chromosomal Location of Human Ortholog: 1q21
Cellular Component: lysosomal lumen; extracellular space; intracellular membrane-bound organelle; membrane; lysosome; extracellular region
Molecular Function: collagen binding; proteoglycan binding; cysteine-type endopeptidase activity; fibronectin binding; laminin binding
Biological Process: adaptive immune response; extracellular matrix organization and biogenesis; antigen processing and presentation of exogenous peptide antigen via MHC class I, TAP-independent; antigen processing and presentation of exogenous peptide antigen via MHC class II; proteolysis; collagen catabolic process; antigen processing and presentation; extracellular matrix disassembly; antigen processing and presentation of peptide antigen via MHC class I; proteolysis involved in cellular protein catabolic process; toll-like receptor signaling pathway; innate immune response; antigen processing and presentation of exogenous peptide antigen via MHC class I; immune response; positive regulation of inflammatory response
