IL-9 Protein, Rat (sf9, His)

IL-9 Protein, with cytokine and receptor binding activities, positively regulates cell growth. Active in the extracellular space, its human orthologs are linked to asthma and respiratory syncytial virus disease. IL-9 expression is biased, notably in testes (RPKM 6.4) and thymus (RPKM 1.0), suggesting involvement in immune and respiratory processes. IL-9 Protein, Rat (sf9, His) is the recombinant rat-derived IL-9 protein, expressed by Sf9 insect cells , with C-His labeled tag.

IL-9 Protein exhibits cytokine activity and interleukin-9 receptor binding activity, playing a role in the positive regulation of cell growth. It is predicted to be active in the extracellular space. Human ortholog(s) of this gene have been implicated in asthma and respiratory syncytial virus infectious disease. The expression of IL-9 is biased, with notable levels observed in testes (RPKM 6.4) and thymus (RPKM 1.0), indicating its potential involvement in immune and respiratory processes.

Measured in a cell proliferation assay using MC/9-2 mouse mast cells. The ED₅₀ for this effect is typically 50-400ng/mL.
