特徴

• 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.
• Recombinant protein corresponding to human IL-7 expressed in E. coli
• Biological Activity:The ED50, as determined by the dose-dependent stimulation of the proliferation of murine 2E8 cells, is ≤0.5ng/ml, corresponding to a specific activity of ≥2x10e6 units/mg.
