This Human Natriuretic Peptide A ELISA Kit from Innovative Research is intended for Quantitative Detection of human NPPA in cell culture supernates, serum and plasma (heparin, EDTA). Strip well format. Reagents for up to 96 tests.

This human NPPA ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for NPPA has been precoated onto 96-well plates. Standards (Expression system for standard: E.coli, Immunogen sequence: N26-R123) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for NPPA is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human NPPA amount of sample captured in plate.

Additional Information: The capture antibody is a monoclonal antibody from mouse, the detection antibody is a biotinylated polyclonal antibody from goat. Expression system for standard: Atrial natriuretic peptide (ANP), also known as NPPA or PND, is a powerful vasodilator, and a protein (polypeptide) hormone secreted by heart muscle cells. This gene is mapped to 1p36.22. It is involved in the homeostatic control of body water, sodium, potassium and fat (adipose tissue). ANP is released by muscle cells in the upper chambers (atria) of the heart (atrial myocytes) in response to high blood volume. It acts to reduce the water, sodium and adipose loads on the circulatory system, thereby reducing blood pressure. ANP has exactly the opposite function of the aldosterone secreted by the zona glomerulosa in regard to its effect on sodium in the kidney – that is, aldosterone stimulates sodium retention and it generates sodium loss.; Immunogen sequence: 369
