Neuron-Specific Enolase (NSE) ELISA Kit
- Created on the 11 May, 2017.
INTENDED USE
Human NSE ELISA kit is a method for analysing in vitro quantitative amounts of neuron specific enolase (gamma-enolase, ENO-2, NSE) in human serum samples. This assay has a minimum sensitivity limit of 0.19 ng/ml.
BACKGROUND
Neuron specific enolase (NSE) which can also be called gamma-enolase (ENO-2) or 2-phospho-D-glycerate hydrolase, is an isoenzyme belonging to the enolase family that consists up of α, β and γ subunits either has a homo or heterodimer. NSE is a 78 kD gamma-homodimer and the majority of this enolase-isoenzyme can be found in neuroendocrine and neuronal tissues. It is essentially a glycolytic enzyme that is able to catalyse the conversion of 2-phosphoglycerate into phosphoenolpyruvate. The biological half-life of NSE in body fluids is about 24 hours and due to the organ-specificity and concentrations of NSE in serum or cerebrospinal fluid (CSF), elevated levels have been identified in diseases which result in relative rapid neuronal destruction. The measurement of NSE concentration in serum of CSF has been useful in assisting the differential diagnosis of a variety of neurodegenerative and neuron-destructive disorders. The following NSE ELISA kit is not designed for screening test for neuroendocrine tumors but can be used to measure levels in established diagnosis. Neuron-specific enolase is useful tumor marker for lung cancer patients.
SENSITIVITY
The minimum detection sensitivity level of gamma-enolase (neuron specific enolase, NSE, ENO-2) using current human NSE ELISA kit was 0.19 ng/ml. The dynamic range for this assay is 7.5 – 115.0 ng/ml.
