IDO Sheep anti-Human, Polyclonal, Invitrogen
Sheep Polyclonal Antibody
Manufacturer: Invitrogen PA140279
PA1-40279 detects Indoleamine 2,3-dioxygenase from human samples. PA1-40279 has been successfully used in ELISA, flow cytometry, immunohistochemistry (paraffin), Western blot, and immunofluorescence applications. A typical starting dilution is 1:50. For Flow cytometry, it is recommended that the polyclonal antibody is used in combination with fixing and permeabilization. The PA1-40279 imunogen is recombit IDO.IDO is an intracellular heme-containing enzyme that catalyzes the oxidative cleavage of the indole ring of several important regulatory molecules, like tryptophan, serotonin, and melatonin. By doing this, IDO initiates the production of biologically active metabolites, commonly referred to as kynurenines. IDO is widely expressed in a variety of human tissues as well as in macrophages and dendritic cells (DCs). In inflammation, interferons (IFNs) act on specific receptors to trigger IDO induction. The production of IFN-gamma and induction of IDO represent important antimicrobial mechanisms. Degradation and depletion of tryptophan by IDO inhibits the growth of viruses, bacteria and parasites. Furthermore, IDO plays a complex and crucial role in immunoregulation during infection, pregcy, autoimmunity, transplantation, and neoplasia. By local depletion of tryptophan and increasing proapoptotic kynurenines, IDO greatly affects T-cell proliferation and survival, both in vitro and in vivo, and also affects B-cell and NK-cell function and survival. There is a central role for IDO expression in tolerance involving regulatory cells and DCs.
