Background

IL-7 plays a key role in lymphopoiesis and lymphoid homeostasis (1). Stromal and epithelial cells within the bone marrow and thymus produce IL-7 (1). The primary targets of IL-7 are T cells, B cells, and dendritic cells (1). IL-7 is crucial for T cell development, the importance of which is underscored by the lack of T cells in both mice and humans that are deficient in IL-7/IL-7R signaling (1,2). While IL-7 appears to be required for B cell development in mice, the role of IL-7 in human B cell development is unclear (1,3). In addition to its effects on T cell lymphopoiesis, IL-7 promotes the maintenance and survival of naïve and memory αβ T cells, as well as γδ T cells (1). The IL-7 receptor is a heterodimer of the common γ chain, γc, and the IL-7-specific IL-7Rα (1). IL-7 activates PI3K/Akt, Jak1/2, and Stat1, 3, and 5 (1).

Endotoxin

Less than 0.01 ng endotoxin/1 μg mIL-7.

Purity

>98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant mIL-7. All lots are greater than 98% pure.

Source / Purification

Recombinant mouse IL-7 (mIL-7) Glu26-Ile154 (Accession #NP_032397) was produced in E. coli at Cell Signaling Technology.

Bioactivity

The bioactivity of recombinant mIL-7 was determined in a 2E8 cell proliferation assay. The ED50 of each lot is between 50-500 pg/ml.
