Intended Use:
Apelin-36 EIA (rat or mouse) is an in-vitro quantitative method designed to determine levels of mouse and rat apelin-36 in samples of plasma, serum, culture media and various other biological fluids samples.

Assay Principle:
1.  Pre-coated microwells 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 TMB substrate solution and hydrogen peroxide to form a blue coloured solution.
4. Reaction is stopped by adding hydrogen chloride, which forms a yellow coloured solution.
5. Intensity of the yellow solution is inversely proportional to the amount of the peptide in standard solutions or samples.
6. Unknown concentration in samples can then be determined by extrapolation from a standard curve.

Apelin 36 levels are increased in left ventricles of patients with chronic heart failure and it known to function as a mediator of the cardiovascular control, which includes blood flow and blood pressure. A potent stimulator of cardiac contractility, playing a vital part in cardiac tissue remodelling which is expressed in various organs such as the brain, heart, lung, kidney, endothelium, gastrointestinal tract , adrenal glands adipose tissue or human plasma.
