Notes
Human Neuronal Pentraxin-1 (NP-I) SimpleStep ELISA® kit is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Neuronal Pentraxin-1 (NP-I) protein in Serum, Cit Plasma, EDTA Plasma, Hep Plasma, Cell culture media, Cerebral Spinal Fluid. Quantitate Human Neuronal Pentraxin-1 (NP-I) with 24.265 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, available in 10-pack (10 x 96-well plates)
-Also available in a fully validated 384-well format.

Sandwich ELISA - Human Neuronal Pentraxin-1 (NP-I) ELISA Kit- Extracellular (ab323496)
Example of human Neuronal Pentraxin-1 standard curve. Background-subtracted data values (mean +/- SD) are graphed.
Sandwich ELISA - Human Neuronal Pentraxin-1 (NP-I) ELISA Kit- Extracellular (ab323496)
Interpolated concentration of native Neuronal Pentraxin-1 was measured in duplicate at different sample concentrations. Undiluted samples are 25% serum, plasma (citrate), plasma (EDTA), and plasma (heparin). The interpolated dilution factor corrected values (to neat sample) are plotted (mean +/- SD, n=2). Sample dilutions are made in 1X Wash Buffer PT.
Sandwich ELISA - Human Neuronal Pentraxin-1 (NP-I) ELISA Kit- Extracellular (ab323496)
Serum of ten individual healthy human male donors was measured in duplicate. Interpolated dilution factor corrected values (to neat sample) are plotted (mean +/- SD, n=2). The mean Neuronal Pentraxin-1 concentration was determined to be 1,922 pg/mL with a range of 818 – 4,218 pg/mL.
Sandwich ELISA - Human Neuronal Pentraxin-1 (NP-I) ELISA Kit- Extracellular (ab323496)
50 ng/mL of recombinant human NPTX2 and NPTXR were individually tested for cross reactivity. Percent reactivity was determined by interpolating the protein concentration from the human Neuronal Pentraxin-1 (NP-I/NPTX1) standard curve and expressing the interpolated concentration as a percentage of the protein concentration tested. No cross reactivity was observed.
Sandwich ELISA - Human Neuronal Pentraxin-1 (NP-I) ELISA Kit- Extracellular (ab323496)
50 ng/mL of recombinant human NPTX2 and 50 ng/mL of recombinant human NPTXR were individually tested for interference with 1,150 pg/mL of recombinant human Neuronal Pentraxin-1 (NP-I/NPTX1). Percent reactivity was determined by interpolating the protein concentration from the human Neuronal Pentraxin-1 standard curve and expressing the interpolated concentration as a percentage of the protein concentration tested. No significant interference was observed.

Example of human Neuronal Pentraxin-1 standard curve in 96-well vs. 384-well plate. Background-subtracted data values (mean +/- SD) are graphed.
Sandwich ELISA - Human Neuronal Pentraxin-1 (NP-I) ELISA Kit- Extracellular (ab323496)
Interpolated concentration of native Neuronal Pentraxin-1 was measured in duplicate at different sample concentrations. Undiluted samples are as follows: 20% cerebrospinal fluid. The interpolated dilution factor corrected values (to neat sample) are plotted (mean +/- SD, n=2). Sample dilutions are made in 1X Wash Buffer PT.
