2-CAT (Noradrenaline/Dopamine) Research ELISA Kit

  • Created on the 3 March, 2017.

BACKGROUND

Noradrenaline which is also more commonly called norepinephrine, is one of the most common neurotransmitter of the sympathetic nervous system that is responsible for reflexive and tonic changes in the cardiovascular tone. It must be noted that the sympathetic noradrenergic system is active all the time even when individuals are in a state of rest, it is working in order to maintain the tonic levels of cardiovascular performance. Naturally occurring norepinephrine are usually found to be made inside the shaft of nerve called nerve axons, they are then stored inside vesicles which are small fluid-filled sacs. They get released during an electrical impulse (action potential), this causes them to travel down the nerve, across the gap between two nerves and bind to a receptor on the second nerve, resulting in stimulating that nerve to respond. Norepinephrine acts mostly on alpha receptors, there have been a few examples where it stimulates beta receptors. One of its most important function is to increase the rate of contractions in the heart and together alongside epinephrine, it underlines the fight-or-flight response.

Dopamine is a neurotransmitter that helps control the brain’s pleasure centres and reward. It can be produced in dopaminergic neurons in the ventral tegmental area (VTA) of the midbrain, arcuate nucleus of the hypothalamus and the substantia nigra pars compacta. Dopamine is the chemical that is found to mediate pleasure within the brain. It is always released during pleasurable situations or it can stimulate one to seek out the pleasurable occupation and activity. Examples include food, sleep, memory, mood, learning, many drugs of abuse and sex. Dopamine can help in focus and attention, vision is able to aid a dopamine response in the brain and this can help one to direct their attention and focus. It is also thought to be responsible for short term memory that is based on an imagined response to certain information. Reduced levels of dopamine in the prefrontal cortex have been found to contribute to a number of attention deficit disorders.

This is a flexible competitive ELISA assay system that is designed for many different biological sample types and volumes. The norepinephrine (noradrenaline) and dopamine are both extracted by using a cis-diol-specific affinity gel, acylated and then converted enzymatically.

INTENDED USE

2-CAT (norepinephrine/dopamine) ELISA kit is a reliable and accurate in vitro quantitative procedure for analysing norepinephrine (noradrenaline) and dopamine in EDTA-plasma, cell culture and many other biological samples types. This assay has a minimum sensitivity detection limit of 0.1 ng/ml (NAD) and 0.25 ng/ml (DOP).

SENSITIVITY

The minimum sensitivity detection limit of norepinephrine (noradrenaline) and dopamine using this 2-CAT (norepinephrine/dopamine) ELISA kit was approximately 0.1 ng/ml (NAD) and 0.25 ng/ml (DOP). The dynamic assay range for this kit is NAD: 0.2 – 32 ng/ml and DOP: 0.5-80 ng/ml.
