Adrenocorticotropic hormone (ACTH, also adrenocorticotropin, corticotropin) is a 39 amino acids polypeptide tropic hormone. ACTH is synthesized from pre-pro-opiomelanocortin (pre-POMC), which is proteolytically cleaved by endopeptidases to yield various polypeptide fragments with varying physiological activity. ACTH is secreted by the anterior pituitary gland. It stimulates secretion of glucocorticoid steroid hormones from adrenal cortex cells, especially in the zona fasciculata of the adrenal glands. It influences steroid hormone secretion by both rapid short-term mechanisms and long-term actions. ACTH is also used as a medication and diagnostic agent.

Standard, Biotinylated ACTH peptide, and Positive Control should be stored at -20°C after arrival. Avoid multiple freeze-thaws. The remaining kit components may be stored at 4°C. Opened Microplate Wells and antibody (Item N) may be stored for up to 1 month at 2° to 8°C. Return unused wells to the pouch containing desiccant pack and reseal along entire edge.
