Additional information


Using L-Glutathione-BSA conjugate (GSH-BSA), antibody specificity was performed by using an ELISA test by competition experiments:

L-Glutathione-BSA Kd around 10-8 M very high affinity and specificity

No crossreactivity with close competitors:

Competitors Affinity compared to GSH-BSA
Oxidized Glutathione-BSA 50 000 times lower no crossreactivity
L-Cysteine-BSA 50 000 times lower no crossreactivity
L-Glutamate-BSA 50 000 times lower no crossreactivity
Reduced Glutathione free 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).

Additional Information

Other Neurotransmitters




Conjugated L-Glutathione


Synthetic L-Glutathione (reduced) 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
