Storage, Stability and Shipping :The lyophilized protein is stable for at least one year from date of receipt at -70oC. Upon reconstitution, this cytokine can be stored in working aliquots at 2o - 8oC for one month, or at -20oC for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Applications :Cell Assay

Endotoxin Level :<1.0 EU/μg of recombinant protein as determined by the LAL method

Molecular Weight :13.5 kDa

Gene Aliases :Lymphocyte chemoattractant factor

Reconstitution Protocol :Reconstitute in sterile PBS at 5 μg/mL

Scientific Background :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.

Sample Cell Assay Data :The ED50 is 7.5-37.5 ng/mL as determined by its ability to chemoattract human CD4+ T lymphocytes (at a concentration range of 1.0-100.0 ng/mL).

Purity :Recombinant Human IL16 resolved on a 15% SDS-PAGE gel under reducing conditions and stained with Coomassie Brilliant Blue G-250
