Recombinant Human IL16

Interleukin 16 (IL16) is a pleiotrophic cytokine derived from CD8+ T-cells that stimulates chemotaxis in CD4+ lymphocytes, monocytes, and eosinophils. It primes CD4+ T-cells for IL2 and IL15 responsiveness, induces T-lymphocyte Interleukin 2 (IL2) receptor expression, and inhibits HIV replication. The signalling process of IL16 is mediated by CD4, and undergoes proteolysis to yield two functional proteins. IL16 isoform 1 has the possible function of acting as a scaffolding protein to anchor ion channels in the membrane, while isoform 3 is involved in cell cycle progression in T-cells and transcriptional regulation of SKP2. IL16 mRNA expression levels have been found in various tissues such as spleen, bone marrow, thymus, and lymph nodes.

Storage Conditions

The lyophilized protein is stable for at least one year from date of receipt at -70°C.
