General description
Indoleamine 2,3-dioxygenase (IDO) is an enzyme that is responsible for converting tryptophan to kynurenines. IDO is expressed by a wide variety of tissues and IDO can be upregulated by interferon gamma. IDO modulates levels of the amino acid tryptophan, which is vital for cell growth, but is also involved in the suppression of the immune response. IDO may be involved in the suppression of the immune response to tumours and blocking the IDO pathway may be a potential target for immunotherapy.
Specificity
Recognizes IDO (Indoleamine 2,3- Dioxygenase), Mr 42 kDa.
Immunogen
GST fusion protein corresponding to residues 78-184 of human Indoleamine 2,3- Dioxygenase (IDO). Clone 10.1.
Application
Anti-IDO (Indoleamine 2, 3-Dioxygenase) Antibody, clone 10.1 is an antibody against IDO (Indoleamine 2 for use in IC & WB.
Immunocytochemistry: A previous lot was used by an independent laboratory in Phoenix cells transfected with an expression vector.
Immunohistochemistry: A previous lot of this antibody was used to detect IDO in human retina, primary eye tumor and metastatic liver tumor tissue sections (Chen, P.W., et al. Experimental Eye Research 85(2007) 617-625).

Interferons have been shown to be potential anti-cancer agents and to inhibit tumor cell growth in culture. The in vivo mechanism of the anti-proliferative effect may be direct or indirect through the immune system; however, in vitro a primary mechanism

Antigen-presenting cells (APCs) can induce tolerance or immunity. We describe a subset of human APCs that express indoleamine 2,3-dioxygenase (IDO) and inhibit T cell proliferation in vitro. IDO-positive APCs constituted a discrete subset identified by coexpression of the cell-surface markers

Immune escape is an early phenomenon in cancer development/progression. Indoleamine 2,3-dioxygenase 1 (IDO1) is a normal endogenous mechanism of acquired peripheral immune tolerance and may therefore be tumor-promoting. This study investigated the clinical relevance of IDO1 expression by immune cells

Allogeneic hematopoietic stem cell transplantation (HSCT) can eradicate chemorefractory leukemia through the graft-versus-leukemia (GVL) activity of donor T cells. However, the clinical success of allo-HSCT is limited by the graft-versus-host disease (GVHD) activity of donor T cells. We have reported
