ANP ELISA Kit (Atrial Natriuretic Peptide)

INTENDED USE

Human ANP ELISA kit is a procedure intended for determining in vitro quantitative amounts of atrial natriuretic peptide (ANP, atrial natriuretic factor, ANF, atrial natriuretic hormone, ANH) in human serum, cell lysates, plasma, other biological fluids and cell culture supernatant. This assay has a minimum sensitivity limit of 4.688 pg/ml.

BACKGROUND

Atrial natriuretic peptide (ANP) can also be referred to as atrial natriuretic hormone (ANH), atrial natriuretic factor (ANF), atriopeptin, cardionatrine and cardiodilatin. It is a 28 amino acid polypeptide hormone which is secreted by heart muscle cells, a powerful vasodilator. It is responsible for reducing the blood pressure by regulating homeostatic control of the body water, fat, sodium and potassium levels. It is often released by muscles cells in the atria of the heart in response to high blood volume. It can be secreted in response to raised sodium concentration, stretching of the atrial wall, endothelin, increased sympathetic stimulation of β-adrenoceptors and exercise.

Atrial natriuretic peptide is able to bind to a specific set of receptors which are called ANP-receptors, this results in reducing blood volume, systemic blood pressure and a reduction in cardiac output. The function is to counter the increase in the volume and pressure of blood that is caused via the renin-angiotensin system.
