Beskrivelse

Recombinant Protein

This product contains purified recombinant human Neuron Specific enolase protein with an N-terminal hexahistidine tag. This product may be used as a positive control in many immunological assays.

Neuron specific enolase (NSE, ENO1, ENO2, ENO3) is an enzyme that catalyzes the conversion of 2-phosphoglycerate to phosphoenolpyruvate in the glycolytic pathway, and the reverse reaction in gluconeogenesis. NSE has a high stability in biological fluids and can easily diffuse to the extracellular medium and cerebrospinal fluid (CSF) when neuronal membranes are injured.NSE is one of three mammalian enolases, which are also known as ENO1, ENO2, and ENO3 or alternately as enolase alpha, beta and gamma. The alpha-subunit is expressed in most tissues, the beta-subunit only in muscle, and the gamma-subunit is expressed primarily in neurons, in normal and in neoplastic neuroendocrine cells. Co-expression of NSE and chromogranin A is common in neuroendocrine neoplasms. Since neurons require a great deal of energy, they are very rich in glycolytic enzymes such a GAPDH and NSE. Antibodies to NSE protein are useful to identify neuronal cell bodies, developing neuronal lineage and neuroendocrine cells. Release of NSE from damaged neurons into CSF and blood has also been used as a biomarker of neuronal injury. NSE is used clinically as a sensitive and useful marker of neuronal damage in several neurological disorders including stroke, hypoxic brain damage, status epilepticus, Creutzfeldt-Jakob disease, and herpetic encephalitis. Further, NSE is found in elevated concentrations in plasma and certain neoplasias that include pediatric neuroblastoma and small cell lung cancer.
