一.產品名稱：Recombinant Human IL-16 (121 a.a.)/重組IL-16

二.Catalog Number:AF-200-16A

三.Synonyms:LCF (Lymphocyte Chemoattractant Factor)

四.Description:

IL-16 is a CD8+ T cell-derived cytokine that induces chemotaxis of CD4+ T cells and CD4+ monocytes and eosinophils. Analysis by gel filtration suggests that, under physiological conditions, hIL-16 exists predominantly as a noncovalently linked multimer, but that some IL-16 may exist as a monomer. However, only the multimeric form appears to possess chemotactic activity, suggesting that receptor cross-linking may be required for activity. IL-16 also induces expression of IL-2 receptor (IL-2R) and MHC class II molecules on CD4 + T cells. Human and murine IL-16 show significant cross-species reactivity. Recombinant human IL-16 is a 12.4 kDa protein consisting of 121 amino acid residues. . Manufactured using all non-animal reagents.
