IL-16 Recombinant Protein (0.05 mg)

This recombinant protein can be used for WB, ELISA, MS and neutralization assays. (Optimal dilution should be determined by user.)

IL-16 was initially identified as a chemotactic cytokine (1), but is now known to possess a wide range of activities. Later studies have more fully characterized IL-16 as an immunomodulatory cytokine that contributes to the regulatory process of CD4+ T cell recruitment and activation at sites of inflammation in association with asthma and several autoimmune diseases (2). The precursor of IL-16 (pro-IL-16) is thought to be cleaved towards the C-terminal region by Caspase-3, releasing a 20 kDa active form that binds to and signals through CD4 (3, 4). Besides acting as a chemotactic cytokine, IL-16 is thought to also be involved in the regulation of T cell proliferation (5) and multiple infectious, immune-mediated, and autoimmune inflammatory disorders including irritable bowel syndrome, systemic lupus erythematosus, and neurodegenerative disorders (6). At least two isoforms of IL-16 are known to exist, the longer isoform (also known as NIL-16) is detected only in neurons of the cerebellum and hippocampus (7). This recombinant protein fragment is derrived from this longer isoform.

Storage: Store at -70C. As with any protein, exposing IL-16 recombinant protein to repeated freeze/thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
