Interleukin 2 (IL-2), a potent lymphoid cell growth factor, plays an important role in both the activation and maintenance of immune responses and in lymphocyte development. IL-2 promotes, for instance, proliferation and differentiation of T cells, NK cells, and B cells.

MACS GMP Recombinant Human IL-2 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.

Biological activity

Background information

IL-2 is a typical four α-helix bundle cytokine and is produced by activated T cells, especially the CD4⁺ T helper cell population. IL-2 signals through a receptor complex consisting of IL-2 receptor α-chain (CD25), β-chain, and common γ-chain.

Applications

MACS GMP Recombinant Human IL-2 can be used for a variety of applications, including the ex vivo activation and expansion of T cells, e.g., antigen-specific cytotoxic T lymphocytes²^,³ or regulatory T cells⁴ or the ex vivo stimulation of NK cells⁵^,⁶.

Technical specifications

Identity/ Molecular mass: 15400 Da, determined by mass spectrometry. This corresponds to the mature form of human IL-2 with a cysteine-to-serine substitution at amino acid sequence position 125 (133 amino acids).
Purity: ≥ 95 % as determined by chip electrophoresis.
Endotoxin content: < 50 EU/mg, as determined by kinetic Limulus Amoebocyte Lysate (LAL) assay (Pharmacopoeia Europaea (Ph. Eur.)).
Residual host cell DNA content: < 150 ng/mg, as determined by quantitative PCR specific for E. coli genomic DNA.
Residual host cell protein content: < 0.5 µg/mg, as determined by E. coli HCP ELISA.
