Monoclonal Anti-Interleukin-7 Receptor α antibody produced in mouse

clone 40131, purified immunoglobulin, lyophilized powder

Synonym: Anti-CD127, Anti-IL-7 Rα



General description

Interleukin-7 (IL-7) is a stromal-cell derived cytokine that is important in the development of adaptive immunity and maintenance of T cells and B cells. IL-7 is produced by bone marrow cells, liver and intestinal epithelia cells, dendritic cells, smooth muscle cells, fibroblasts macrophages and keratinocytes. The effect of IL-7 is mediated by IL-7 receptor consisting of an α chain and a γ chain and by the subsequent activation of JAK/STAT, PI3K and Src kinases. Important roles of IL-7 include proliferation of lymphoid progenitors, survival and homeostasis of naïve and memory T cells
Monoclonal Anti-Interleukin-7 receptor α recognizes recombinant human IL-7Rα (approximately 55-65 kDa). In immunoblotting, the antibody shows approximately 5% cross-reactivity with recombinant human IL-10R, recombinant human IL-2R, recombinant human IL-5R α, and recombinant human IL-6R.


purified recombinant human IL-7 receptor α extracellular domain, expressed in insect Sf 21 cells.


Anti-Interleukin-7 receptor α antibody may be used for immunoblotting at a working concentration of 1-2 μg/ml. For ELISA the working concentration recommended is 0.5-1.0 μg/ml.

Physical form

Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline containing 5% trehalose.
