ACTH 11-24, a fragment of the adrenocorticotropic hormone, is primarily utilized in research settings to study the mechanisms of hormone-receptor interactions. It is often employed in biochemical assays to investigate the binding affinity and specificity of ACTH receptors, particularly in the context of adrenal gland function. This peptide fragment is also used in immunological studies to produce antibodies that can help in the detection and quantification of ACTH in various biological samples. Additionally, ACTH 11-24 serves as a tool in endocrinology research to explore the regulation of cortisol production and its role in stress response. Its applications extend to the development of diagnostic assays and potential therapeutic agents targeting disorders related to adrenal insufficiency or hyperactivity.
