rHu IL-7 outfitted for closed-system manufacturing.
See why everyone is choosing Akron cytokines.
Akron’s Recombinant Human Interleukin-7 (rHu IL-7) Closed System Solutions (CSS)™ is manufactured following all relevant cGMP guidelines for ancillary materials. The rHu IL-7 active substance is supported by a Type II Master File (MF) on file with the FDA, which can be referenced during your drug or biologic application process.
Akron’s rHu IL-7 is a single chain, 17.5 kDa, non-glycosylated cytokine analog expressed in E. coli, containing 153 amino acids. The downstream purification process uses a multi-step orthogonal approach, without the use of affinity tags, to minimize exogenous impurities and ensure the delivery of highly purified and active substance for further manufacturing applications.
The liquid rHu IL-7 CSS product is packaged in a sterile fluoropolymer bag with two different weldable tubing connection options, allowing for easy incorporation into modern closed-system cell culture bioprocessing protocols. rHu IL-7 CSS increases safety and ease of use by eliminating the reconstitution step during manufacture and allows for the introduction of cytokine material into culture media in a fully contained manner to maximize sterility. Sterile filtration and aseptic filling are followed by Endotoxin and Sterility testing performed per USP/EP on the final product. See product Packaging features below.

IL-7 is primarily expressed by non-marrow-derived stromal and epithelial cells and is required for early T cell development inside the thymus and for T cell homeostasis and regeneration in the periphery. It promotes the differentiation of hematopoietic stem cells (HSCs) down the lymphoid cell lineage and optimizes T celldendritic cell interaction. The dimeric IL-7 receptor protein (IL-7R) shares an identical subunit with the IL-2, IL-15, and IL-21 receptor proteins and activates some of the same signal transduction mechanisms. IL-7 is currently being investigated as an immunotherapy agent for various malignancies as well as HIV infection. Akron’s cGMP-compliant rHu IL-7 can be used to stimulate proliferation of cytotoxic T lymphocytes (CTLs), B lymphocyte cells, monocytes, NK cells, and LAK cells.
