Summary
A sensitive, specific and reproducible radioimmunoassay was developed for the measurement of alpha-melanocyte-stimulating hormone (α-MSH) in the blood plasma of rat. The assay method is based on a sensitive antiserum raised against α-MSH in rabbit. The serum is highly specific to α-MSH; a HPLC study of an extract of rat plasma showed that the immunoreactivity was given by α-MSH. The basal level of α-MSH, measured after a simple extraction with ethanol, was found to be 168.3 ± 16.3 pg/ml (x; ± SEM). Ether and lysine-vasopressin appeared to be potent stimuli for the peripheral release of α-MSH.
