Additional information


Using Kynurenic acid-BSA conjugate (KYNA-BSA), antibody specificity was performed by using an ELISA test by competition experiments:

Kynurenic acid-BSA Kd around 10-8 M very high affinity and specificity

No crossreactivity with close competitors:

Competitors Affinity compared to KYNA-BSA
L-Kynurenine-BSA 6 000 times lower very low affinity
Quinolinic acid-BSA 50 000 times lower no crossreactivity
Picolinic acid-BSA 50 000 times lower no crossreactivity
Quinaldic acid-BSA 50 000 times lower no crossreactivity
Xanthurenic acid-BSA 50 000 times lower no crossreactivity
Anthranilic acid-BSA 50 000 times lower no crossreactivity
3-Hydroxy-Anthranilic acid-BSA 50 000 times lower no crossreactivity
L-Tryptophan-BSA 50 000 times lower no crossreactivity
L-Phenylalanine-BSA 50 000 times lower no crossreactivity

The antibody recognizes the conjugated form of the small molecule, not the free form (see protocol for specific tissue preparation).

Conjugated Kynurenic acid


Synthetic Kynurenic acid conjugated to bovine serum albumin (BSA)

Species reactivity

The antibody recognizes the target in all species, vertebrates (included humans) and invertebrates, because of the universality of the small molecule


Polyclonal antibody was preabsorbed on protein carriers and purified by ammonium sulfate precipitation
