Details

What it is

Residues 4 to 7 of adrenocorticotropic hormone with a proline-glycine-proline tail added. The fragment itself has none of the corticotropic activity of the parent hormone, since the sequence that binds the melanocortin-2 receptor is not present.

Also sold as: ACTH 4-7 PGP, Met-Glu-His-Phe-Pro-Gly-Pro

Reconstitution and handling

Handling

  • As suppliedLyophilised powder
  • Sealed, refrigeratedMonths
  • In solutionRefrigerate, use short-term

Concentration is mass divided by the volume you added. A 10mg vial made up to one millilitre of solvent gives 10mg per millilitre; to two millilitres, half that. Record the volume you used: a solution whose concentration is not written down is a solution you cannot use quantitatively.

The full procedure is on our reconstitution guide, with a concentration calculator; what is known about keeping these materials is on storage and stability. Bacteriostatic water and acetic acid are both in our catalogue and can be ordered with a product or on their own.
