MACS® GMP Recombinant Human IL-7

Interleukin 7 (IL-7) is a pleiotropic cytokine with central roles in modulating T cell development and peripheral T cell homeostasis. IL-7 can act both as a T cell growth factor as well as a critical anti-apoptotic survival factor for naive and memory T cells.
MACS GMP Recombinant Human IL-7 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

The primary sources of IL-7 are non-hematopoietic stromal cells in bone marrow, thymus, and lymphoid organs and tissues. IL-7 is a member of the type I cytokine family. It is related to IL-2 and signals through a heterodimeric receptor composed of the common cytokine signaling γ-chain and IL-7 receptor α-chain.

Applications

MACS GMP Recombinant Human IL-7 can be used for a variety of applications, including the
ex vivo
generation of antigen-specific cytotoxic T lymphocytes.

Technical specifications
  • Identity/ Molecular mass: 17.382 Da, determined by mass spectrometry. This corresponds to the mature form of human IL-7 (152 amino acids).
  • Purity: ≥ 95 % 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: < 5 µg/mg, as determined by E. coli HCP ELISA.

Biological activity

  • The specific activity is determined by proliferation assay according to Ishihara
    et al.1
    using mouse 2E8 cells. The proliferation assay was calibrated with the reference standard for human IL-7 (NIBSC code 90/530) provided by the National Institute for Biological Standards and Control.
  • Minimal specific activity: ≥ ≥ 5×
