Target Details

Target: MSH alpha

Alternative Name: alpha-MSH

Background:

Gene Symbols: STAMBP, AMSH

Background: Alpha-Melanocyte-stimulating hormone (alpha-MSH), a proteolyic cleavage product from ACTH (1-13), is an endogenous peptide hormone and neuropeptide of the melanocortin family. It is a non-selective full agonist of the melanocortin receptors MC1, MC3, MC4, and MC5, but not MC2. Alpha-MSH is important for pigmentation primarily of the hair and skin. It also plays a role in feeding behavior, energy homeostasis, sexual activity, and protection against ischemia and reperfusion injury.

In this assay, a biotinylated Alpha-MSH peptide is spiked into the samples and standards. The samples and standards are then added to the plate, where the biotinylated Alpha-MSH peptide competes with endogenous (unlabeled) Alpha-MSH for binding to the anti-Alpha-MSH antibody. After a wash step, any bound biotinylated Alpha-MSH then interacts with horseradish peroxidase (HRP)- streptavidin, which catalyzes a color development reaction. The intensity of the colorimetric signal is directly proportional to the amount of captured biotinylated Alpha-MSH peptide and inversely proportional to the amount of endogenous Alpha- MSH in the standard or samples. A standard curve of known concentration of Alpha-MSH peptide can be established and the concentration of Alpha-MSH peptide in the samples can be calculated accordingly.
