The RIG-I ELISA kits listed below are analytical tools for measuring concentrations of RIG-I in various samples. RIG-I is an alternative name for the human RIGI gene, which encodes the protein, RNA sensor RIG-I. It has been mentioned that RIG-I plays a role in innate immune responses, among other functions. Structurally, the RIGI protein is 925 amino acid residues in length and 106.6 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cytoplasm of the cell. This protein is known to be ubiquitinated, sumoylated, cleaved and phosphorylated. Other names for this target antigen include DDX58, DDX58, and RIG1.
