Intended Use:
Alpha MSH fluorescent EIA (human, mouse, rat) is designed to measure in-vitro quantitative concentrations of alpha melanin concentrating hormone (alpha MCH) using samples of  serum, plasma, CSF, culture media, tissue homogenate and any biological fluid samples and urine.

Assay Principle:
1. The microwell plates have 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 extrapolation from a standard curve.

Cross Reactivity:
Alpha MSH (Human, Mouse, Rat) 100%.
Des Ac-alpha-MSH 79%.
alpha-MSH (4-13) (Ac-(Cys4, d-Phe7, Cys10)  16.3%.
AGRP (83-132)-NH2 (Human) 0%.
Leptin (Human)  0%.
Neuropeptide Y (Rat, Human)  0%.
ACTH (Human)  0%.
CART (55-102)(Human)  0%.

Melanocyte Stimulating Hormones (Alpha-MSH) is an important melanocortin for pigmentation and it functions to stimulate the production/release of melanin by melanocytes in the skin and hair. It belongs to a group called the melanocortins, which also includes ACTH, beta-MSH, beta MSH and alpha MSH. All of these are peptide hormones that are produced by cells in the intermediate lobe of the pituitary gland.
