QSOX1 ELISA kits are immunoassay tools for the measurement of the protein quiescin sulfhydryl oxidase 1, which is encoded by the QSOX1 gene in humans. Functionally, this protein is known to catalyze the oxidation of sulfhydryl groups in peptide and protein thiols to disulfides with the reduction of oxygen to hydrogen peroxide. The canonical protein structure is reported to have an amino acid length of 747 residues, a mass of 82.6 kDa, and is a member of the Quiescin-sulfhydryl oxidase (QSOX) protein family. It is known to be localized in the golgi and is secreted and is found to be expressed in heart, placenta, lung, liver, skeletal muscle, pancreas and very weakly in the brain and kidney. As many as 2 protein isoforms have been reported. The protein has been noted to be post-translationally O-glycosylated and N-glycosylated. Other alias names for this target include QSCN6, sulfhydryl oxidase 1, quiescin Q6 sulfhydryl oxidase 1, testis tissue sperm-binding protein Li 62n, thiol oxidase 1, and Q6.
Some QSOX1 ELISA kits can detect targets at levels as low as 10 ng/L and as high as 20 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
