Interleukin-7 (IL-7) is a hematopoietic growth factor that primarily affects early-stage B and T cells.IL-7 is produced by thymic stromal cells, splenocytes, and keratinocytes, and, in combination with other factors, such as ConA and IL-2, also co-stimulates the proliferation of mature T cells. Human and mouse IL-7 are cross-species responsive. Recombinant Human IL-7, supplied as Lyophilized powder, is highly active, pure and low in endotoxin.
