Name of the Test:

Beta Melanocyte Stimulating Hormone ( β MSH )

Alias Names:

Beta MSH

Clinical Applications:

Beta Melanocyte Stimulating Hormone is a 22 amino acid peptide produced from the prohormone, Proopiomelanocortin. One of the fragments of Proopiomelanocortin is b-Lipotropin which is further fragmented to form gammaLipotropin and betaEndorphin.The gamma Lipotropin is then cleaved to form beta MSH.The major biological property of beta MSH is hyperpigmentation. Beta MSH is the major melanocortin in human.Beta-Melanocyte Stimulating hormone has been found in high levels in patients with Cushings disease, ectopic ACTH producing tumors and also in some non-endocrine tumors.


Samples are extracted and assayed by an immunometric assay (Sandwich ELISA assay).
