These P113 ELISA kits are immunodetection tools for measuring the levels of P113 in biological samples. P113 is an alias of the human STAT2 gene, which encodes the protein, signal transducer and activator of transcription 2. Notably, P113 is known to play a role in viral immune response and the regulation of transcription, among other functions. The STAT2 protein is 851 amino acid residues in length and 97.9 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. This protein is known to be ubiquitinated and phosphorylated. Other names for this target antigen include IMD44 and ISGF-3.
