Induced production of TNF-α from human PBMC cells for Human IL-32 α. Cell proliferation was measured to calculate the ED50.
Non-reducing (-) and reducing (+) conditions in a 4 - 20% Tris-Glycine gel stained with Coomassie Blue. 1 μg of protein was loaded in each lane. Human IL-32 α has a predicted Mw of 14.9 kDa.

Interleukin-32 α (IL-32 α) is one of six known splice variants of the IL-32 gene. IL-32 α induces the macrophage production of inflammatory cytokines, such as interleukin-8 (IL-8), Tumor Necrosis Factor α (TNF-α), and Macrophage Inflammatory Protein 2 (MIP-2). IL-32 α expression is increased after the activation of T cells, Natural Killer (NK) cells, and interferon γ-treated epithelial cells.

Activity Assay

Human IL-32 α is fully biologically active when compared to standard. The activity is determined by the induced production of TNF-α from human PBMC cells.
