Isolation of melanotropins and vasopressin from neuro-intermediate lobes of bovine pituitary glands. A simplified procedure

Abstract
A simplified procedure for the isolation of .alpha.-melanotropin, .beta.-melanotropin and arginine-vasopressin from the acid acetone extract of posterior-intermediate lobes of bovine pituitaries was described. It involves essentially 2 steps: gel filtration on Sephadex G-10 and high performance liquid chromatography.
