Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation,

Specificity / Sensitivity

IRG1 (D6H2Y) Rabbit mAb recognizes endogenous levels of total IRG1 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly460 of human IRG1 protein.

Western Blotting

Western Blotting

Western blot analysis of lysates from THP-1 untreated (-) or treated with TPA (#4174, 50ng/ml) for 24 hours then LPS (5ug/ml) for 6 hours in fresh medium (+), using IRG1 (D6H2Y) Rabbit mAb (upper) or GAPDH (14C10) Rabbit mAb #2118 (lower).


IRG1 (Immune-responsive gene 1) is one of the most up-regulated genes in macrophages under proinflammatory conditions (1). It is also highly expressed in the pregnant uterus during implantation (2,3). IRG1 is a cis-aconitate decarboxylase that produces itaconic acid by decarboxylating cis-aconic acid, an intermediate of the tricarboxylic acid cycle (4). Itaconic acid is an endogenous inhibitor of succinate dehydrogenase, linking macrophage metabolic rewiring and regulation of inflammation (5,6).
