Human IL-32 alpha is one of approximately 6 splice variants of a gene cloned from the human lung carcinoma stable transfectant, A549-Rbeta. IL-32 alpha has been shown to induce IL-8, TNF-a, and MIP-2 production from human & mouse macrophage cell lines. It is upregulated in activated T- & NK-cells, and IFN-g-treated epithelial cells.

Biological Activity:
Human IL-32 alpha activity is measured via the dose-dependent induction of TNF-alpha production from human PBMCs. The ED50 is in the range of 0.101-152ng/ml.
