Description
Glu-1-Fibrinopeptide B Peptide Mass Standard is a lyophilized standard that is useful for the tuning and calibration of electrospray ionization and MALDI mass spectrometers. Glu-1-Fib has an amino acid sequence of EGVNDNEEGFFSAR (monoisotopic mass = 1569.65 Da), and under acidic conditions it produces a +1 ion (m/z 1570.6) and a +2 ion (m/z 785.8). The Glu-1-Fib Peptide Mass Standard is Certified Mass Spec Grade and is provided in convenient, lyophilized vials for easy reconstitution and usage.
