Cinnabarinic acid detection by IHC in human breast tumorImmunohistochemical staining of human breast tumor tissue shows presence of Cinnabarinic acid in cells surrounding a necrotic area. Paraffin-embedded tumor tissue was subjected to pH=6 antigen retrieval before overnight incubation with primary anti-Cinnabarinic antibody (1/500 dilution). A polymer-conjugated secondary Ab was added and immunostaining was revealed using DAB.
Cinnabarinic acid detection by IHC in human caudate putamenIHC staining highlights the presence of Cinnabarinic acid in glial cells of the caudate-putamen region in human brain tissue. Paraffin-embedded tissue section was subjected to pH=6 antigen retrieval followed by overnight incubation with primary antibody (dilution 1/500). After incubation with polymer-conjugated secondary Ab, DAB was used to visualize the staining.

Cinnabarinic acidCinnabarinic acid is a downstream metabolite of the kynurenine pathway wich is produced by condenstaion of two molecules of 3HAA. It was recently presented as an Aryl Hydrocarbon Receptor ligand driving IL-22 production. Also, Cinnabarinic acid was found to act as an orthosteric agonist of type-4 metabotropic glutamate (mGlu4) receptor 4, featuring anti-inflammatory activity.

The first and only validated anti-Cinnabarinic acid antibody available for research use. IHC validation of this mouse mAb in human brain and breast tumor tissues revealed the presence, in specific cells, of Cinnabarinic acid, a tryptophan metabolite known for its immunomodulatory role. A 2020 paper also used this anti-cinnabarinic antibody to stain mouse brain tissue sections (immunofluorescence).
