Quinolinic acid detection in human parkinson's brain
Immunohistochemistry (IHC) reveals the presence of Quinolinic acid in glial cells in human parkinsonian midbrain tissue. Paraffin-embedded tissue section was subjected to pH=9 antigen retrieval followed by overnight incubation with primary anti-quinolinic acid polyclonal antibody (dilution 1/1000). After incubation with polymer-conjugated secondary Ab, DAB was used to visualize the staining.

Validated for IHC in human brain tissues, the anti-Quinolinic acid (QUIN) rabbit polyclonal antibody proved to work at 1/1000 dilution on paraffin-embedded sections, a single vial thus catering for approximately 200 stainings.
