Monoclonal Rat IgG2A Clone # 373802
Protein A or G purified from hybridoma culture supernatant
E. coli-derived recombinant human IL‑32 alpha
Accession # NP_001012651
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Scientific Data

Western Blot Detection of Human IL-32a antibody by Western Blot. View Larger

Detection of Human IL‑32 alpha by Western Blot. Western blot shows lysates of human peripheral blood mononuclear cells (PBMC) treated (+) with 200 ng/mL Ionomycin and 10 ng/mL PMA for 72 hours. PVDF Membrane was probed with 2 µg/mL of Human IL-32a Monoclonal Antibody (Catalog # MAB30401) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for IL-32a at approximately 30 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Immunocytochemistry IL-32a antibody in Human PBMCs by Immunocytochemistry (ICC). View Larger

IL‑32 alpha in Human PBMCs. IL-32a was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Human IL-32a Monoclonal Antibody (Catalog # MAB30401) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (yellow; Catalog # NL013) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Background: IL-32 alpha

IL-32 alpha is the shortest and most abundant of four potential splice variants of the proinflammatory cytokine IL-32 (previously called NK4) with a predicted unmodified size of 15 kDa. Potential modifications include myristoylation and N-glycosylation. Transfected IL-32 alpha was more likely to be cell-associated as compared to IL-32 beta, suggesting an intracellular function. IL-32 is induced by mitogens in peripheral lymphocytes, by IFN‑ gamma in epithelial cells, or by IL-12 with IL-18 in NK cells and in turn Induces cytokine expression. No ortholog has been found in mouse.
