Additional information

Specifity

Using 5-DL-Methoxytryptophan-BSA conjugate (MTrp-BSA), antibody specificity was performed by using an ELISA test by competition experiments:

5-DL-Methoxytryptophan-BSA Kd around 10-8 M very high affinity and specificity

Very low affinity or no crossreactivity with close competitors:

Competitors Affinity compared to MTrp-BSA
L-Tryptophan-BSA 5800 times lower very low affinity
5-Hydroxy-L-Tryptophan-BSA 50 000 times lower no crossreactivity
5-Methoxytryptamine-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)
