Adrenaline (Epinephrine)

Dopamine

Noradrenaline

 

3-Methoxytyramine

Metanephrine

Normetanephrine

Clinical relevance

The catecholamines adrenaline (epinephrine), noradrenaline (norepinephrine) and dopamine are biogenic amines, which play a central role in the body as hormones and neurotransmitters. Adrenaline and noradrenaline are produced in the adrenal medulla and the sympathetic nervous system. Dopamine is a neurotransmitter in the brain and acts as a local messenger substance in the peripheral nervous system.

 

Product advantages

  • Short analysis time of less than 6 minutes
  • No changes to setup are needed due to identical column and mobile phase

 

This assay enables the combined determination of catecholamines together with metanephrines in urine (2020/COMBI). It is an exceptionally sensitive and reliable method for detecting pheochromocytomas with an analysis time of less than 6 minutes. The highly selective separation column and the optimised mobile phase are used for the analysis of both catecholamines and metanephrines, so no change of the chromatographic system is required. The established specific sample preparation using solid phase extraction guarantees simple and safe handling and reproducible results.
