HumanKine™ IL-9

Recombinant human IL-9 expressed in engineered human cells. IL-9 is a 38 to 48 kDa monomeric glycoprotein and belongs to the IL -7/IL-9 protein family. IL-9 is expressed by a subset of T-helper cells identified as Th9 cells which may regulate chronic allergic inflammation. IL-9 increases the proliferation of T lymphocytes, mast cells and erthroid precursor cells.
