Proadrenomedullin (45-92), human, a mid-regional fragment of proadrenomedullin (MR-proADM), comprises amino acids 45-92 of pre-proADM. Proadrenomedullin (45-92), human has a longer half-life, is relatively stable and is produced in equimolar amounts to adrenomedullin (ADM), making it a surrogate for plasma levels of ADM gene products[1][2].
