General Notes
This product (Catalog No. DPABH-19213) is a rabbit-derived IgG polyclonal antibody raised against human CTSS, targeting the amino acid region 121–250 of the protein. This antibody exhibits cross-reactivity with CTSS from mouse, rat, dog, horse, and rabbit. It has been affinity purified by Protein A. The preproprotein encoded by this gene, a member of the peptidase C1 family, is a lysosomal cysteine proteinase that participates in the degradation of antigenic proteins to peptides for presentation on MHC class II molecules. The mature protein cleaves the invariant chain of MHC class II molecules in endolysosomal compartments and enables the formation of antigen-MHC class II complexes and the proper display of extracellular antigenic peptides by MHC-II. The mature protein also functions as an elastase over a broad pH range. When secreted from cells, this protein can remodel components of the extracellular matrix such as elastin, collagen, and fibronectin. This gene is implicated in the pathology of many inflammatory and autoimmune diseases and, given its elastase activity, plays a significant role in some pulmonary diseases. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.
DPABH-19213 is suitable for use in IHC-P (1:100–1:500), IHC-F (1:100–1:500), IF (immunofluorescence) (1:100–1:500), ELISA (1:5,000–1:10,000) applications.
DPABH-19213 is supplied as a liquid formulation in 0.01M TBS (pH7.4) with 1% BSA, 0.02% Proclin300 and 50% Glycerol. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
