The oprL ELISA kits listed below are analytical tools for measuring concentrations of oprL in various samples. oprL is an alternative name for the human OPRL1 gene, which encodes the protein, opioid related nociceptin receptor 1. Structurally, the OPRL1 protein is 370 amino acid residues in length and 40.7 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cytoplasmic vesicles and cell membrane of the cell. In terms of tissue specificity, it is notably expressed in blood leukocytes. This protein is known to be phosphorylated and glycosylated. Other names for this target antigen include KOR-3, KOR3, and NOCIR.
