Norepinephrine ELISA kits are assays designed to detect the organic small molecule norepinephrine, which functions as a hormone and a neurotransmitter. It is also known as noradrenaline. This compound functions to mobilize the body for action and becomes elevated at times of stress or danger. It elevates heart rate and blood pressure, while promoting vigilance, restlessness and anxiety. Norepinephrine interacts with several receptors and transporters, including alpha and beta adrenergic receptors, vesicular monoamine transporter, and the norepinephrine transporter.
