Intended Use:
ANP-alpha chemiluminescent EIA (human, ovine, canine) is an invitro quantitative method for analysing amounts human, canine and ovine atrial natriuretic peptide alpha (ANP-alpha) using samples of plasma, serum, culture media, any biological fluid samples, urine, CSF and tissue homogenate.

Assay Principle:
1. Microwell plate has been pre-coated with secondary antibody and also the non-specific binding sites have been blocked.
2. Secondary antibody is able to bind with the Fc fragment of the primary antibody, the Fab segment is competitively bound by both biotinylated peptides and the peptide standard or the targeted peptide in samples.
3. Biotinylated peptide can then interact with the SA-HRP, which then catalyzes the substrate solution.
4. Luminescence intensity is directly proportional to the amount of biotinylated peptide-SA-HRP complex but inversely proportional to the amount of the peptide in standard solutions or samples.
5. Unknown concentration in samples can then be determined by extrapolation from a standard curve.

Cross Reactivity:
alpha-ANP (1-28) (Human, Ovine, Canine) 100%.
beta ANP (Human) 100%.
ANP (Rat) 0%.
CNP-22  (Porcine, Rat, Human) 0%.
BNP-26 (Porcine) 0.1%.
BNP-32 (Human)  0%.
Endothelin-1 (Rat, Human, Mouse, Bovine, Canine)  0%.
BNP-45 (Rat)  0%.

Background:
Atrial natriuretic peptide (ANP) is a 28 amino acid peptide with a 17 amino acid ring in the middle of the molecule which is vital role in the homeostatic control of body water, adiposity and sodium. It functions to lower the sodium, water and adipose loads on the circulatory system, thereby reducing blood pressure. It is released by atrial myocytes, muscle cells in the atria of the heart, in response to high blood pressure.
