Adrenocorticotropic Hormone (ACTH) (1-39), human is a melanocortin receptor agonist.
Adrenocorticotropic Hormone (ACTH) (1-39), human (ACTH 1-39), a member of the melanocortin family, stimulates production of CS by the adrenals, but melanocortin receptors are also found in the central nervous system (CNS) and on immune cells. ACTH 1-39 protects neurons in vitro from several apoptotic, excitotoxic and inflammation-related insults[1]. The conditioned medium (CM) is prepared from untreated astroglia (AS) cultures and from AS cultures treated with 200 nM ACTH 1-39 for 24 h, washed to remove ACTH 1-39, then incubated for another 24 h in DMEM. In initial experiments, no difference is found in oligodendroglia (OL) viability in the presence of OL definedmediumwith 2% newborn calf serum (NCS) or AS CM (prepared in DMEM with no serum). After 24 h, OL death under each condition varies between 1 and 4%. Similar results for OL viability are obtained with microglia (MG) CM. In subsequent experiments, controls in each experiment consist of OL in defined medium with 2% NCS[2].

Cell experiment: | For analysis of the effects of ACTH 1-39 or CM on oligodendroglia (OL) death, purified OL cultures are incubated with ACTH 1-39 at 200 nM or the various CM for 30 min before addition of the toxic agents. Cell death is assessed after 1 day using trypan blue uptake as the indicator of cell death. Trypan blue is considered a preferred method for measurement of total cell death compared to terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL), which measures only apoptosis, or live/dead fluorescent assays, which may not detect permeable dead cells with degraded DNA, thus underestimating cell death. Differentiated OL are identified by their characteristicmorphology, that is, rounded or oval birefringent cells with multiple lacy branching processes, and in some cases by immunostaining with antibodies to galactolipids[2]. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
