CellGenix® rh IL-7
GMP and Preclinical grade
CellGenix Recombinant Human IL-7 supports the survival, proliferation and differentiation of T cells and enhances survival of natural killer cells (NK cells). CellGenix rh IL-7 is produced in our dedicated animal-free facility ensuring maximum safety for optimal use in ATMP manufacturing.
Interleukin-7 (IL-7) is a cytokine that promotes the differentiation of pluripotent hematopoietic stem cells (HSCs) into lymphoid progenitor cells. Furthermore it supports proliferation of various cells in the lymphoid lineage (B cells, T cells and NK cells). It is secreted mainly by stromal cells in the bone marrow and thymus.
IL-7 is used in the cell and gene therapy space for the ex vivo expansion of genetically modified T cells, such as CAR T cells, and differentiation of induced pluripotent stem cells (iPSCs) into T cells. It is in addition used to differentiate cord blood derived hematopoietic stem cells (HSCs/CD34+) into NK cells.
CellGenix Recombinant Human IL-7 is produced following all applicable GMP guidelines and allows for the safe use in accordance with USP Chapter <1043> and Ph. Eur. General Chapter 5.2.12.
Our GMP cytokines are provided with documented evidence of purity, potency, consistency and stability. In combination with our expert regulatory and technical support this will help simplify your raw material qualification and validation efforts.

Storage & Stability
Store lyophilized cytokine at -20°C to -80°C.
Store a 250 µg/ml reconstituted cytokine solution:
• 4 weeks at 2°C to 8°C under sterile conditions after reconstitution. Store in the original container.
• 4 months at -20°C to -80°C under sterile conditions after reconstitution. Store in 60 µl aliquots in polypropylene cryogenic vials.
Avoid repeated freeze/thaw cycles.
CellGenix GMP rh IL-7 has an activity of 50 – 200 × 106 IU/mg
The activity of GMP rh IL-7 was measured in a cell proliferation assay using the IL-7-dependent cell line IxN/2b. It was calibrated against NIBSC #90/530.
You can find the batch specific activity on the certificate of analysis (CoA).
