Quinolinic acid detection in human midbrain by immunohistofluorescence (IHF)
Immunofluorescence staining highlights nuclear exclusion of Quinolinic acid in human midbrain. Paraffin-embedded brain tissue section was subjected to pH=9 antigen retrieval followed by overnight incubation with primary anti-Quinolinic acid antibody (dilution 1/250). After incubation with Alexa-555 conjugated secondary Ab, epifluorescence microscopy (100X) was used to visualize the staining.
