CTSE ELISA kits are immunoassay tools for the measurement of the protein cathepsin E, which is encoded by the CTSE gene in humans. Functionally, this protein is suspected to have a role in immune function. The canonical protein structure is reported to have an amino acid length of 396 residues, a mass of 42.8 kDa, and is a member of the Peptidase A1 protein family. It is known to be localized in the endosome and is noted to be expressed abundantly in the stomach, the Clara cells of the lung and activated B-lymphocytes, and at lower levels in lymph nodes, skin and spleen. As many as 3 protein isoforms have been reported. The protein has been noted to be post-translationally glycosylated and cleaved. Other alias names for this target include erythrocyte membrane aspartic proteinase, slow-moving proteinase, and CATE.
The detection range for different CTSE ELISA kits can vary, with some assays measuring target concentrations as low as 14 pg/mL and as high as 40 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
