Adrenocorticotropic hormone fragment 1-10 human (ACTH) is primarily used in research settings to study the physiological and biochemical roles of ACTH in the human body. It is particularly valuable in investigating the mechanisms of hormone regulation, stress responses, and the hypothalamic-pituitary-adrenal (HPA) axis. Researchers utilize this fragment to understand how specific segments of the ACTH molecule influence receptor binding and biological activity, which can provide insights into developing targeted therapies for endocrine disorders. Additionally, it serves as a tool in studying the effects of ACTH on steroidogenesis and its potential implications in conditions like adrenal insufficiency or Cushing's syndrome. This fragment is also employed in immunological studies to explore its antigenic properties and potential use in diagnostic applications.
