Interleukin 15 (IL-15) is a potent lymphoid cell growth factor and stimulates the proliferation of activated T cells and the generation of cytotoxic T lymphocytes (CTLs). IL-15 also induces the generation, activation, and proliferation of NK cells.
MACS GMP Recombinant Human IL-15 is designed for
ex vivo
cell culture processing. No animal- or human-derived materials were used for the manufacture of this product, unless otherwise stated in the respective Certificate of Origin. The product is lyophilized without carrier protein or preservatives.

Detailed product information

Background information

IL-15 is a member of the four α-helix bundle cytokine family. It is produced by different cell types, including epithelial cells, monocytes, muscle and placenta cells. In addition to its ability to activate T cells and NK cells, IL-15 is also important for B cell growth and immunoglobulin production as well as for the maintenance of CD8
+
memory T cells. For binding and signaling IL-15 uses the unique IL-15 receptor α-chain, but shares the β- and γ-chain of the IL-2 receptor.

Applications

MACS GMP Recombinant Human IL-15 can be used for a variety of applications, including the
ex vivo
generation of cytotoxic T lymphocytes
2,3
or the
ex vivo
stimulation of NK cells
4,5
.
Technical specifications
  • Identity/ Molecular mass: 12.770 Da, determined by mass spectrometry. This corresponds to the mature form of human IL-15 (114 amino acids).
  • Purity: ≥ 95 % as determined by chip electrophoresis.
  • Product related impurities: ≤ 10 % as determined by chip electrophoresis.
  • Endotoxin content: < 100 EU/mg, as determined by kinetic Limulus Amoebocyte Lysate (LAL) assay (Pharmacopoeia Europaea (Ph. Eur.)).
  • Residual host cell DNA content: < 20 ng/mg, as determined by quantitative PCR specific for E. coli genomic DNA.
  • Residual host cell protein content: < 10 µg/mg, as determined by E. coli HCP ELISA.

Biological activity

  • The specific activity is determined by proliferation assay according to Soman
    et al.1
    using CTLL-2 cells. The proliferation assay was calibrated with the reference standard for human IL-15 (NIBSC code 95/554) provided by the National Institute for Biological Standards and Control.
  • Minimal specific activity: ≥ 7×
