Background of Cathepsin S
Cathepsin S, also known as CTSS, is a protein that in humans is encoded by the CTSS gene. A member of the peptidase C1 family, CTSS gene is a lysosomal cysteine proteinase that may participate in the degradation of antigenic proteins to peptides for presentation on MHC class II molecules. By fluorescence in situ hybridization(FISH), this gene is mapped to 1q21.3. The encoded protein can function as an elastase over a broad pH range in alveolar macrophages. The bond-specificity of this proteinase is in part similar to the specificities of cathepsin L and cathepsin N.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Human Cathepsin S PicoKine® Quick ELISA Kit within the same batch/lot to ensure the consistency of the kits' performances. ELISA intra assay consistency is measured using wells from the same plate/assay kit. ELISA inter assay consistency is measured using wells from different plates from the same batch production/lot.

Reproducibility
We ensure reproducibility by testing three samples with differing concentrations of Cathepsin S in ELISA kits from four different production batches/lots.
Reproducibility
To assay reproducibility, three samples with differing target protein concentrations were assayed using four different lots.
