title: The ACTH-releasing hormone of the hypothalamus requires a co-factor.
abstract: Gel filtration of an extract of rat median eminence tissue in 0.1 N HCl on Sephadex G-25 separated two peaks, both with feeble ACTH-releasing activity. Full activity of the extract was regained when both peaks were recombined. This observation suggests that the ACTH-releasing hormone of the hypothalamus requires a co-factor for activity.
