Storage & Safety

Storage Store at 4 deg C until reconstitution. Following reconstitution aliquot and freeze at -20 deg C for long term storage. Avoid repeated freeze/thaw cycles.
Endotoxin Levels Endotoxin level is less than 0.1 ng per ug (1 EU/ug).

General Information

Biological Significance IL9 is an immunoregulatory cytokine produced by IL2 activated Th2 lymphocytes. IL9 enhances the proliferation of T lymphocytes, mast cells, erthroid precursor cells and megakaryoblastic leukemia cell lines. Over-expression of IL9 has been implicated in the pathogenesis of anaplastic lymphoma and Hodgkin's disease. Whereas Mouse IL9 can function on human cells, human IL9 is inactive on mouse cells.
