Additional information


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

DL-Octopamine-BSA Kd around 10-8 M Very high affinity and specificity

Very low affinity or no crossreactivity with close competitors:

Competitors Affinity compared to Octo-BSA
Tyramine-BSA 400 times lower low affinity
Noradrenaline-BSA 10 000 times lower no crossreactivity
Tyrosine-BSA 50 000 times lower no crossreactivity
Dopamine-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).

Additional Information

Host species









Conjugated DL-Octopamine


Synthetic DL-Octopamine 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
