ACTH (1-13) is a 13-aa peptide, with cytoprotective effects in the model of ethanol induced gastric lesions in rats.
体外研究 (In Vitro)
Adrenocorticotropic hormone (ACTH) is a tropic hormone produced by the anterior pituitary, regulates cortisol and androgen production and is associated with Addison disease, Cushing syndrome and Cushing disease[2].

体内研究 (In Vivo)
ACTH (1-13) alone or in combination with met-enkephalin shows potent cytoprotective effects in the model of ethanol induced gastric lesions in rats, and has immunomodulatory effects[1].

Negative (lt;0)
1.;;Try to dissolve the peptide in water first. 2.;;If water fails, add NH4OH (lt;50 μL). 3.;;If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (gt;0)
1.;;Try to dissolve the peptide in water first. 2.;;If water fails, try dissolving the peptide in a 10%-30% acetic acid solution. 3.;;If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO.
Zero (=0)
1.;;Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first. 2.;;For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.
