Intended Use:
Human AGRP Form C-Amide Fluorescent EIA kit can be used to measure levels of human agouti-related protein (71-132) amide levels quantitatively using samples of  any biological fluid samples, serum, plasma, urine and CSF.

Assay Principle:
1. Human AGRP form c-NH2 fluorescent EIA kit 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. Fluorescence 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 using this human AGRP form c-NH2 fluorescent EIA kit to extrapolation from a standard curve.

Background:
Agouti-related peptide (AGRP) is paracrine signalling molecule which is composed of 112 amino acids. AGRP has been shown to be an inverse agonist of melanocortin receptors, specifically, MC3-R and MC4-R. Overexpression in transgenic mice results in obesity and hyperphagia. It found to be mainly expressed in the following: hypothalamus, adrenal gland, subthalamic nucleus. Understanding the function AGRP plays in weight gain could assist in help reduce obesity. It increases appetite and decreases metabolism and energy expenditure.
