Purity

> 97 % pure by SDS-PAGE and HPLC

Endotoxin Level

Less than 0.1 EU/ug of IL-9 as determined by LAL method.

Predicted Molecular Mass

14.2 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Activity

IL-9 protein is fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine TS1 cells is less than 0.02 ng/ml, corresponding to a specific activity of > 5.0 x 10^7 IU/mg.

Background: IL-9

IL-9 is a cytokine with immunoregulatory function, produced by activated T-helper type 2 lymphocytes. It acts on various cell types such as T- and B-lymphocytes, mast cells, haemopoietic progenitors and megakaryoblastic leukemia cell lines. IL-9 stimulates cell proliferation and prevents apoptosis. IL-9 may play a role in the pathogenesis of diseases such as certain lymphomas (Hodgin's disease, anaplastic lymphoma) and asthma. Although murine IL-9 can act on human cells, human IL-9 is inactive on mouse cells.
