名称：原装正品| Recombinant Rat IL-7
Source: E.coli. Human and murine IL-7 is cross-species reactive. Recombinant rat IL-7 is a 15.0 kDa protein containing 130 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 < 2.0 ng/ml, corresponding to a specific activity of > 5 x 106 units/mg.
