50 µg specific antibody, lyophilized. Affinity purified with the immunogen. Albumin and azide were added for stabilization. For reconstitution add 50 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use.
Antibodies should be stored at +4°C when still lyophilized. Do not freeze!

Adrenocorticotropic hormone (ACTH), also known as corticotropin, is a 39 amino acid peptide hormone. It is synthesized from the precursor POMC (pro-opiomelanocortin). POMC is proteolytically processed in a cell type specific manner to generate a couple of small biologically active peptides including ACTH (1,2).
ACTH is mainly produced and secreted by corticotroph cells of the anterior pituitary in response to corticotropin-releasing hormone from the hypothalamus. ACTH acts on the adrenal cortex of the adrenal gland to stimulate the production of glucocorticoids like cortisol. ACTH plays a pivotal role in homeostasis and stress response and is a key component of the hypothalamic-pituitary-adrenal (HPA) axis (2,3).
ACTH is also produced in extra-pituitary sites like hypothalamus and skin, where further processing of ACTH leads to the generation of alpha melanocyte-stimulating hormone (α-MSH) (2).
An excess of ACTH can cause Cushing's syndrome whereas ACTH deficiency can result in secondary adrenal insufficiency (3,4).
