- IL-7 is a hematopoietic growth factor which affects primarily early B and T cells. Produced by thymic stromal cells, spleen cells and keratinocytes, IL-7 can also co-stimulate the proliferation of mature T cells in combination with other factors such as ConA and IL-2. Human and murine IL-7 is cross-species reactive. Recombinant human IL-7 is a 17.4kD protein containing 153aa residues. Manufactured using all non-animal reagents. Recombinant protein corresponding to human IL-7 expressed in E. coli. Biological Activity: Determined by its ability to stimulate the proliferation of mouse 2E8 cells. The expected ED50 is ≤0.5ng/ml, corresponding to a specific activity of ≥2x1e6units/mg.
