名称：原装订购| Recombinant Human IL-9
Source: E.coli. Over-expression of IL-9 has been implicated in the pathogenesis of anaplastic lymphoma and Hodgkins disease.
Purity: Greater than 98% by SDS-PAGE gel and HPLC analyses. IL-9 is an immunoregulatory cytokine produced by IL-2 activated Th2 lymphocytes.
Description: IL-9 enhances the proliferation of T lymphocytes, mast cells, erthroid precursor cells and megakaryoblastic leukemia cell lines. Whereas murine IL-9 can function on human cells, human IL-9 is inactive on mouse cells. The ED50 as determined by the dose-dependent proliferation of human M07e cells was ≤ 0.2 ng/ml, corresponding to a specific activity of ≥ 5 x 106 units/mg.
