Additional information

Specifity

Using Dopamine-BSA conjugate (DA-BSA), antibody specificity was performed by using an ELISA test by competition experiments:

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

Very low affinity with close competitors:

Competitors Affinity compared to DA-BSA
Noradrenaline-BSA 200 times lower low affinity
L-DOPA-BSA 400 times lower low affinity
Octopamine-BSA 400 times lower low affinity
Tyramine-BSA 5000 times lower very low affinity
Adrenaline-BSA 5000 times lower very low affinity

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

IgG1

Target

Conjugated Dopamine

Immunogen

Synthetic Dopamine 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

Purity

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

Form

Lyophilized

Stabilizers / preservatives

None

Storage instructions and buffer

Lyophilized vial must be stored at 4°C in a dry area up to 2 years after receipt. After reconstitution with 50% of distilled water and 50% of glycerol, the aliquot must be stored at -20°C, and is stable at least for 2 years. Avoid freeze-thaw cycles
