  • Product overview

    Human Neuron specific Enolase ELISA Kit (ab217778) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Neuron specific Enolase protein in cell culture extracts, cell culture supernatant, cit plasma, edta plasma, hep plasma, serum, and tissue extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Neuron specific Enolase with 23 pg/ml sensitivity.


    SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:


            - Single-wash protocol reduces assay time to 90 minutes or less
            - High sensitivity, specificity and reproducibility from superior antibodies
            - Fully validated in biological samples
            - 96-wells plate breakable into 12 x 8 wells strips


    A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

  • Notes

    Neuron-specific Enolase (also known as NSE, gamma-enolase and Enolase 2) is a cytoplasmic phosphopyruvate hydratase.  Neuron-specific Enolase has two related family members, Enolase 1 and Enolase 3.  Neuron-specific Enolase can be used to identify neuronal cells and normal or malignant cells with neuroendocrine origin.

    Abcam has not and does not intend to apply for the REACH Authorisation of customers’ uses of products that contain European Authorisation list (Annex XIV) substances.
    It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.

  • Function

    Has neurotrophic and neuroprotective properties on a broad spectrum of central nervous system (CNS) neurons. Binds, in a calcium-dependent manner, to cultured neocortical neurons and promotes cell survival.
  • Tissue specificity

    The alpha/alpha homodimer is expressed in embryo and in most adult tissues. The alpha/beta heterodimer and the beta/beta homodimer are found in striated muscle, and the alpha/gamma heterodimer and the gamma/gamma homodimer in neurons.
  • Pathway

    Carbohydrate degradation; glycolysis; pyruvate from D-glyceraldehyde 3-phosphate: step 4/5.
  • Sequence similarities

    Belongs to the enolase family.
  • Developmental stage

    During ontogenesis, there is a transition from the alpha/alpha homodimer to the alpha/beta heterodimer in striated muscle cells, and to the alpha/gamma heterodimer in nerve cells.
  • Cellular localization

    Cytoplasm. Cell membrane. Can translocate to the plasma membrane in either the homodimeric (alpha/alpha) or heterodimeric (alpha/gamma) form.
