Product Summary

The Quantikine® Human NT-ProANP Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human NT-ProANP in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human NT-ProANP and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human NT-ProANP showed linear curves that were parallel to the standard curves obtained using the Quantikine® kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human NT-ProANP.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components

Recovery

The recovery of human NT-ProANP spiked to levels throughout the range of the assay was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 104 87-114
EDTA Plasma (n=4) 102 84-120
Heparin Plasma (n=4) 98 84-111
Serum (n=4) 108 95-122

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human NT-ProANP were diluted with calibrator diluent to produce samples with values within the dynamic range of the assay.

ELISA Quantification of Atrial Natriuretic Peptide in Endothelin-treated Cardiomyocytes using the Human NT-ProANP Quantikine ELISA View Larger

Endothelin Induces Expression of Atrial Natriuretic Peptide in iPSC-derived Cardiomyoctyes. JOY6 human iPSCs were differentiated into beating cardiomyocytes. After 21 days of differentiation cardiomyocytes were treated with 5 nM of Endothelin-1 (Catalog # 1160) for 25.5 hours to induce cardiac hypertrophy. The level of secreted Pro-Atrial Natriuretic peptide (ANP), which is known to be elevated during cardiac hypertrophy, was assessed using the Human NT-ProANP Quantikine® ELISA Kit (Catalog # DANP00). As expected, detection of Pro-ANP was increased in Endothelin-1 treated cells.

Background: Atrial Natriuretic Peptide/ANP

Atrial Natriuretic peptide (ANP) is synthesized as a 151 aa preproprotein. The proprotein contains cardiodilatin (aa 26 - 92) and atrial natriuretic factor (ANF; aa 124 - 151) which become active after processing by the serine protease corin. ANP is primarily synthesized in the heart and is secreted in response to atrial distention. ANF circulates in the plasma, eliciting natriuretic, diuretic, vasorelaxant and antimitogenic effects directed toward reduction of body fluid and blood pressure regulation. ANF acts through the cGMP-coupled NP receptor A. Human ANP and ANF share 84% and 96% aa identity with mouse ANP and ANF, respectively.
