CSTA ELISA kits are immunoassay tools for the measurement of the protein cystatin A, which is encoded by the CSTA gene in humans. Functionally, this protein is an intracellular thiol proteinase inhibitor. The canonical protein structure is reported to have an amino acid length of 98 residues, a mass of 11 kDa, and is a member of the Cystatin protein family. It is known to be localized in the cytoplasm and is reported to be expressed in the skin throughout the epidermis. The CSTA gene has been associated with the disease, Peeling skin syndrome. Other alias names for this target include PSS4, STF1, STFA, cystatin A (stefin A), cystatin AS, and AREI.
There are CSTA ELISA kits that can detect a target at concentrations as low as 6.5 pg/mL and as high as 100 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
