Predicted Molecular Mass:14.1 kDa SDS-PAGE:30-35 kDa, reducing conditions Activity:Measured in a cell proliferation assay using TS1 mouse helper T cells. Uyttenhove, C. et al. (1988) Proc. Natl. Acad. Sci. 85:6934. The ED₅₀ for this effect is typically 3-15 ng/mL. Molecule Information: IL-9 Long Name: Interleukin 9 Entrez Gene IDs: 3578 (Human); 16198 (Mouse) Background: IL-9 Mouse interleukin 9 (IL-9) was originally identified as T cell-derived T cell growth factor III/P40 that could support the long term growth of certain mouse T helper clones in the absence of antigen or antigen-presenting cells. Human IL-9 was independently cloned as a novel growth factor that is mitogenic for the human megakaryoblastic leukemic cell line, M07e. Human and mouse IL-9 share 56% identity at the amino acid level. Although mouse IL-9 is active on human cells, human IL-9 is not active on mouse cells.
