Human IDO PharmaGenie ELISA Kit (SBRS0692)

An immunoassay tool for quantifying indoleamine 2,3-dioxygenase (IDO) protein in human samples, this ELISA kit from Assay Genie supports immunology, oncology, and cell-biology research laboratories. IDO is a heme-containing enzyme that catalyzes the rate-limiting step of tryptophan catabolism through the kynurenine pathway, and is implicated in tumor immune escape, transplant tolerance, inflammatory disease, and interferon-gamma-driven signaling studies.

The kit is configured for 96 assays and validated with human-derived matrices including cell culture supernatants and blood-derived fractions. Each package includes a pre-coated microplate, ready-to-use reagents, and a complete protocol. Standard curve dilutions and sample replicates support reproducible quantification across the assay's working range.

Reagents should be refrigerated upon arrival, equilibrated to room temperature before use, and protected from light to preserve stability. Researchers apply this assay in studies of monocyte-derived dendritic-cell maturation, tumor-microenvironment profiling, autoimmune inflammation, and infectious-disease models where IDO activity is a biomarker of interest.
