These U2AF65 ELISA kits are immunodetection tools for measuring the levels of U2AF65 in biological samples. U2AF65 is an alias of the human U2AF2 gene, which encodes the protein, U2 small nuclear RNA auxiliary factor 2. Notably, U2AF65 is known to play a role in mRNA processing and RNA splicing, among other functions. The U2AF2 protein is 475 amino acid residues in length and 53.5 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus of the cell. Other names for this target antigen include .
