CTSB ELISA kits are immunoassay tools for the measurement of the protein cathepsin B, which is encoded by the CTSB gene in humans. Functionally, this protein is reported to be a thiol protease, which is believed to participate in intracellular degradation and turnover of proteins. The canonical protein structure is reported to have an amino acid length of 339 residues, a mass of 37.8 kDa, and is a member of the Peptidase C1 protein family. It is known to be localized in the lysosomes and cell membrane and is reported to be expressed in the stratum spinosum of the epidermis. The protein has been noted to be post-translationally glycosylated. The CTSB gene has been associated with the disease, Keratolytic winter erythema. Other alias names for this target include CPSB, KWE, RECEUP, APP secretase, amyloid precursor protein secretase, cathepsin B1, cysteine protease, and APPS.
The detection range for different CTSB ELISA kits can vary, with some assays measuring target concentrations as low as 10 ng/L and as high as 1200 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
