H-Met-Arg-Phe-Ala-OH

Catalog No.: GA22724Purity:>97.00%
MRFA is used as a calibration standard in mass spectrometry (ESI). Miao et al. studied Pt(II) complexes of the tetrapeptide by mass spectrometric methods. MRFA has been shown to be a competitive inhibitor of an enkephalin-generating endopeptidase isolated from rat brain. The peptide is a substrate for dipeptidyl peptidase III from human erythrocytes and for snapalysin.
