    Test principle

    The INNOTEST NPTX2 is a solid-phase enzyme immunoassay in which the neuronal pentraxin-2 protein is captured by a first monoclonal antibody, 33F9 (ADx409; IgG1). CSF samples are added and incubated with a biotinylated antibody, 22H10 (ADx410; IgG2a). This antigen-antibody complex is then detected by a peroxidase-labeled streptavidin. After addition of substrate working solution, samples will develop a color. The color intensity is a measure for the amount of human neuronal pentraxin-2 protein in the sample1,2.

    Test principle INNOTEST NPTX2

    Test principle INNOTEST NPTX2 (SV= streptavidin; HRP= horseradish peroxidase).

     
    Background

    Neuronal pentraxin-2 is a synaptic protein that consistently shows decreased CSF concentrations in Alzheimer’s disease compared to control subjects1,2. Preliminary studies indicate that while CSF NPTX2 correlates poorly with the core CSF biomarkers (β-amyloid and tau) and other synaptic markers, it seems to correlate well with cognitive decline2.
