These KOX ELISA kits are immunodetection tools for measuring the levels of KOX in biological samples. KOX is an alias of the human NOX4 gene, which encodes the protein, NADPH oxidase 4. Notably, KOX is known to play a role in cardiac muscle cell differentiation and carbohydrate metabolism and homeostasis, among other functions. The NOX4 protein is 578 amino acid residues in length and 66.9 kilodaltons in mass. However, as many as 9 protein isoforms have been identified. It is localized to the ER and cell membrane of the cell. In terms of tissue specificity, it is noted to be expressed by distal tubular cells in kidney cortex and in endothelial cells. This protein is known to be N-glycosylated. Other names for this target antigen include .
