These FIP2 ELISA kits are immunodetection tools for measuring the levels of FIP2 in biological samples. FIP2 is an alias of the human OPTN gene, which encodes the protein, optineurin. Notably, FIP2 is known to play a role in autophagy pathways and Golgi organization, among other functions. The OPTN protein is 577 amino acid residues in length and 65.9 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the cytoplasmic vesicles, golgi, and cytoplasm of the cell. This protein is known to be phosphorylated. Other names for this target antigen include ALS12 and GLC1E. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
