名称：原装订购| Recombinant Human IL-2
Source: E.coli. IL-2 stimulates growth and differentiation of B-cells, NK cells, lymphokine activated killer cells, monocytes, macrophages and oligodendrocytes. Recombinant human IL-2 is a 15.5 kDa protein, containing 134 amino acid residues including one intrachain disulfide bond.
Purity: Greater than 98% by SDS-PAGE gel and HPLC analyses. IL-2 is a powerful immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation.
Description: The ED50 as determined by the dose-dependent stimulation of murine CTLL-2 cells is ≤ 0.1 ng/ml, corresponding to a specific activity of ≥ 1 x 107 units/mg. IL-2/IL-2R signaling is required for T-cell proliferation and other fundamental functions which are essential for the immune response.
