Product Specific Information

Description:
This eyedio monoclonal antibody reacts with human indoleamine-2,3-dioxygenase (IDO, INDO, IDO1), an intracellular enzyme that catalyzes the degradation of tryptophan to kynurenines. IDO is expressed in a wide variety of tissues and cells, including macrophages, plasmacytoid dendritic cells, and several cell lines. IDO can be induced in many different cell types by IFN gamma or other inflammatory stimuli. Expression of IDO in antigen presenting cells and tumors is thought to mediate immune suppression through depletion of this essential amino acid and/or by the creation of tryptophan metabolites that cause apoptosis of T cells and induction of regulatory T cells.

Applications Reported:
This eyedio antibody has been reported for use in intracellular staining followed by flow cytometric analysis.

Applications Tested:
This eyedio antibody has been pre-titrated and tested by intracellular staining and flow cytometric analysis of stimulated normal human peripheral blood cells using the Intracellular Fixation and Permeabilization Buffer Set (Product # 88-8824-00) and protocol.
Please refer to BestProtocols®: Protocol A: Two step protocol for (cytoplasmic) intracellular proteins.
This antibody can be used at 5 µL (0.06 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10⁵ to 10⁸ cells/test. It is recommended that the antibody be carefully titrated for optimal performance.

Target Information

IDO1 is an intracellular heme-containing enzyme that catalyzes the oxidative cleavage of the indole ring of several important regulatory molecules such as tryptophan, serotonin, and melatonin. By doing this, IDO1 initiates the production of biologically active metabolites, commonly referred to as kynurenines.
IDO1 is widely expressed in various human tissues as well as in macrophages and dendritic cells. In inflammation, interferons (IFNs) act on specific receptors to trigger IDO1 induction. The production of IFN-gamma and induction of IDO1 represent important antimicrobial mechanisms. Degradation and depletion of tryptophan by IDO1 inhibit the growth of viruses, bacteria, and parasites. Furthermore, IDO1 plays a complex and crucial role in immunoregulation during infection, pregnancy, autoimmunity, transplantation, and neoplasia.
