Listed are ELISA Kits for the detection of QSOX, an alias name of quiescin sulfhydryl oxidase 1. The human protein, encoded by the gene QSOX1, is 747 amino acid residues long and has a mass of 82,578 daltons. However, there are up to 2 reported isoforms. It is an enzyme of the thiol oxidase class and is a member of the Quiescin-sulfhydryl oxidase (QSOX) family. This protein is reported to have a secreted cellular localization, and is glycosylated. This target may also be known as: sulfhydryl oxidase 1, quiescin Q6 sulfhydryl oxidase 1, testis tissue sperm-binding protein Li 62n, thiol oxidase 1, and quiescin Q6 sulfhydryl oxidase 1.
