Analysis Note

Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The specific activity of Recombinant Human IL-15 is approximately 4.5 x 105 U/μg, which is calibrated against recombinant human IL-15 WHO International Standard (NIBSC code: 95/554).

Physical form

Lyophilized from 0.2 μm filtered solution in phosphate buffered saline, pH 7.4 with 50 μg bovine serum albumin per 1 μg as a carrier protein.

Biochem/physiol Actions

IL-15 (interleukin 15) is a proinflammatory pleiotropic cytokine and is a connection between innate and adaptive immune responses. It participates in the proliferation, survival and activation of various lymphocytes lineages. IL-15 works by associating with a high affinity heterotrimeric receptor complex containing IL-15Rα, IL-2/15Rβ and IL-Rγ. It is present in different forms, the soluble form, the hyper IL-15 formed by association between IL-15 receptor α chain and soluble cytokine, and the membrane bound isoform.
