Overview
Interleukin 7 (IL-7) is a member of the type I cytokine family that is critical for T and B cell development and survival. It is produced by non-hematopoietic cells in the thymus, lymphoid organs, and by bone marrow stromal cells (Lundström et al.). IL-7 binds to a receptor (IL-7R) composed of common gamma chain and IL-7Ra (CD127) and signals through the JAK/STAT and PI3K pathways. IL-7 regulates the survival of naïve and memory CD4+ and CD8+ T cells, γδ T cells, NK T cells, innate lymphoid cells, and regulatory T cells (Carrette & Surh). Although a deficiency in IL-7R still permits the generation of normal numbers of peripheral B cells in humans, stimulation of human B cell precursors with IL-7 could promote STAT5-dependent proliferation and survival in vitro (Clark et al.; Corfe & Paige). This product is animal component-free.

Data
(A) The biological activity of Human Recombinant IL-7, ACF was tested by its ability to promote the proliferation of 2E8 cells. Cell proliferation was measured using a fluorometric assay method. The EC50 is defined as the effective concentration of the cytokine at which cell proliferation is at 50% of maximum. The EC50 in the example above is 0.769 ng/mL. (B) 1 μg of Human Recombinant IL-7, ACF was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized by Coomassie Blue staining. Human Recombinant IL-7, ACF has a predicted molecular mass of 17.5 kDa.
