Indoleamine 2,3-dioxygenase/IDO antibody in A431 Human Cell Line by Immunocytochemistry (ICC).

Indoleamine 2,3-dioxygenase/IDO in A431 Human Cell Line.

Indoleamine 2,3-dioxygenase/IDO was detected in immersion fixed A431 human epithelial carcinoma cells stimulated with 0.5 ng/mL of Recombinant Human IFN-gamma (Catalog # 285-IF) using Mouse Anti-Human Indoleamine 2,3-dioxygenase/IDO Monoclonal Antibody (Catalog # MAB6030) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counter-stained with DAPI (blue). Specific staining was localized to cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.
Detection of Indoleamine 2,3-dioxygenase/IDO antibody in Human MDSCs antibody by Flow Cytometry.

Detection of Indoleamine 2,3‑dioxygenase/IDO in Human MDSCs by Flow Cytometry.

Human PBMC-derived myeloid-derived suppressor cells (MDSCs) treated with 10 ng/mL Recombinant Human IL-6 (Catalog # 206-IL) and 10 ng/mL Recombinant Human GM-CSF (Catalog # 215-GM) for 7 days were stained with Mouse Anti-Human Siglec-3/CD33 APC-conjugated Monoclonal Antibody (Catalog # FAB1137A) and either (A) Mouse Anti-Human Indoleamine 2,3-dioxygenase/IDO Monoclonal Antibody (Catalog # MAB6030) or (B) Mouse IgG1Isotype Control (Catalog # MAB002) followed by Phycoerythrin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0102B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin. View our protocol for Staining Intracellular Molecules.
Detection of Indoleamine 2,3-dioxygenase/IDO antibody in Human Monocytes antibody by Flow Cytometry.

Detection of Indoleamine 2,3‑dioxygenase/IDO in Human Monocytes by Flow Cytometry.

Human Monocytes were selected from PBMC using MagCellect Human CD14+ Cell Isolation Kit (Catalog # MAGH105) and cultured overnight with (A) 50 ng/mL Recombinant Human MCSF (Catalog # 216-MC), 50 ng/mL Recombinant Human IFNg (Catalog # 285-IF) and 50 ng/mL LPS, or (B) Recombinant Human MCSF alone. Cells were stained with Mouse Anti-Human Indoleamine 2,3-dioxygenase/IDO Monoclonal Antibody (Catalog # MAB6030) followed by APC-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B) and Mouse Anti-Human CD14 PE-conjugated Monoclonal Antibody (Catalog # FAB3832P). Quadrant markers were set based on Mouse IgG1 Isotype Control (Catalog # MAB002). To facilitate intracellular staining, cells were fixed with 1% paraformaldehyde and permeabilized with saponin.

Background: Indoleamine 2,3-dioxygenase/IDO

Indoleamine 2,3-dioxygenase (IDO) is a heme-containing intracellular dioxygenase catalyzing the degradation of the essential amino acid L-tryptophan to N-formyl-kynurenine (1). This degradation is the first and rate-limiting step of the L-kynurenine pathway (2). IDO is widely expressed in dendritic cells, macrophages, microglia, eosinophils, fibroblasts, endothelial cells, and most tumor cells. In immune cells, its expression is mainly induced by cytokines such as IFN-gamma, IFN-alpha, IFN-beta, and IL‑10. IDO has an antimicrobial function due to its decreasing the availability of the essential amino acid tryptophan in inflammatory environments (3). Recent studies have demonstrated that IDO induces immunosuppression during infection, pregnancy, transplantation, autoimmunity, and neoplasia (3-5).
