Human GABA ELISA kit is designed for determining in vitro quantitative concentrations of gamma aminobutyric acid (GABA) in human plasma, serum and urine samples. This assay has a minimum sensitivity detection limit of 49 ng/ml.
Gamma aminobutyric acid (GABA) is an inhibitory neurotransmitter, which functions to slow down or weaken neuron signals. It occurs naturally within the brain where it is vital in regulating the brain activity, there is also evidence to supports its important role in regulating muscle tone. Very small amounts are obtained from food, however, the majority of it is synthesised from glutamate in the body.
Due to its inhibitory function, GABA plays a vital plays role in anxiety. In this situation, when nerve signals fire too quickly and possess anxiety-inducing signals, it is activated and acts in order to slow the signals down and therefore reducing overwhelming feelings of anxiety. In individuals with anxiety disorders (e.g. post traumatic stress, panic disorder and generalised anxiety), it does not function as it should and this results in elevated levels of anxiety.
