Acth (6-24)

ACTH (6-24) (human) (Adrenocorticotropic hormone (6-24)) is an ACTH fragment. ACTH (6-24) (human) is a competitive inhibitor of steroidogenesis induced by ACTH (1-39) and ACTH (5-24) (Kd:13.4 and 3.4 nM). ACTH (6-24) (human) inhibits corticosterone production and cAMP accumulation induced by hPTH 1-34[1][2].
