Source: E.coli. Human and murine IL-7 is cross-species reactive. Recombinant human IL-7 is a 17.4 kDa protein containing 153 amino acid residues.
Purity: Greater than 98% by SDS-PAGE gel and HPLC analyses. IL-7 is a hematopoietic growth factor which affects primarily early B and T cells.
Description: 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. The ED50 was determined by the dose-dependent stimulation of the proliferation of murine 2E8 cells is ≤ 0.5 ng/ml, corresponding to a specific activity of ≥ 2 x 106 units/mg.
