Anti-Neuron-Specific Enolase (NSE), Mouse monoclonal，200UL，SAB4200571-200UL，Sigma

General description

Monoclonal anti-neuron-specific enolase (NSE) (mouse IgG1 isotype) is derived from the hybridoma NSE-P1 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice. Neuron specific enolase (NSE) belongs to the family of enolase enzymes. Enolases have three subunits (a, b, and g), which can combine to form five different isoenzymes: aa, ab, ag, bb, and gg. Enolase 1 (aa) is present in adipose tissue, kidney, liver, and spleen. Enolase 3 (bb) is muscle specific. Enolase 2 (ENO2), also known as neuron-specific enolase (NSE) is a cytoplasmic enzyme, that is released during cell destruction and has a half-life of approximately 30 hours in serum. This dimeric enzyme (gg) is found in neurons and in neuroendocrine cells. ENO2 gene is mapped to human chromosome 12p13.

Immunogen

synthetic peptide corresponding to a sequence at the C-terminal region of human NSE.¹ The isotype is determined by ELISA using Mouse Monoclonal Antibody Isotyping Reagents (Sigma ISO-2).

Application

Anti-Neuron-Specific Enolase (NSE), Mouse monoclonal has been used in:

• immunofluorescence staining
• immunocytochemistry
• immunofluorescence microscopy
• immunoblotting
• enzyme-linked immunosorbent assay (ELISA)
• immunohistochemistry

Biochem/physiol Actions

Enolase 2 (ENO2) participates in glycolysis by converting β-glycerophosphate into dihydroxyacetone phosphate. It serves as a neurobiochemical marker of brain damage after traumatic brain injury, anoxic encephalopathy, stroke, and cardiac arrest. NSE also acts as a circulating marker for neuroendocrine tumors. High levels of NSE is observed in breast cancer upon exposure to arsenite and cadmium.
Monoclonal Anti- Neuron-Specific Enolase (NSE) recognizes human, rat, and mouse NSE.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Preparation Note

For extended storage, freeze at –20 °C in working aliquots. Repeated freezing and thawing or storage in “frost-free” freezers is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.
