Product details:
Human ACTH ELISA Kit (adrenocorticotropic hormone) ab267814 is a rapid single-wash 90-min Sandwich ELISA to measure Human ACTH (adrenocorticotropic hormone)in citrate plasma, EDTA plasma, heparin plasma, serum. This SimpleStep sensitivity is 1.2 pg/mL.
How the assay works
Human ACTH (adrenocorticotropic hormone)SimpleStep ELISA
employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA
plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA
protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA
kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

ACTH, adrenocorticotropic hormone, is a peptide hormone cleavage product of the POMC protein produced by the pituitary gland. ACTH plays an important role in stress and circadian rhythm signaling. ACTH's primary action is on the adrenal cortex, where its binding induces the secretion of glucocorticoid steroid hormones.

Adrenocorticotropic hormone (ACTH) also known as corticotropin is a peptide hormone secreted by the pituitary gland. It is a 39-amino acid polypeptide with a molecular mass of approximately 4540 Da. ACTH is primarily expressed in the anterior pituitary gland and smaller amounts can be found in the central nervous system. Its production and secretion are tightly regulated by corticotropin-releasing hormone (CRH) through a feedback mechanism involving the hypothalamic-pituitary-adrenal (HPA) axis.
Biological function summary
Adrenocorticotropic hormone stimulates the adrenal cortex to produce and release glucocorticoids especially cortisol. ACTH is not part of a larger complex but acts as a singular hormone in its pathway. The hormone also influences the expression of certain enzymes important for steroid biosynthesis. In addition to its role in the adrenal cortex ACTH can mildly interact with melanocortin receptors on adipose tissues contributing to lipolysis and inflammatory processes.
Pathways
Adrenocorticotropic hormone functions in the HPA axis one of the body's key stress response systems. The hormone also involves in the regulation of the corticosteroid biosynthesis pathway. The primary protein it interacts with in these processes is cortisol which in turn regulates many physiological processes including immune response and metabolism. ACTH and cortisol form a feedback loop where elevated cortisol levels inhibit the release of both CRH and ACTH.
Increased or decreased levels of adrenocorticotropic hormone can result in disorders such as Cushing's disease and Addison's disease. Cushing's disease is characterized by overproduction of ACTH often due to pituitary adenomas leading to excess cortisol production. Conversely in Addison’s disease inadequate ACTH or adrenal cortex dysfunction leads to insufficient cortisol production. Both conditions highlight the disrupted feedback relationship between ACTH and cortisol resulting in significant clinical symptoms that require careful management.
