Using oa-Tof MS and Maximum Entropy to Obtain Accurate Molecular Masses on a Variety of Glycoproteins: A Demonstration of Sub 3 ppm Mass Accuracies on Species Above 30 kDa
Here we demonstrate accurate mass measurement of the isoforms
of a glycoprotein (34 kDa) using an internal calibrant and Maximum
Entropy (MaxEnt) deconvolution of the data obtained on an orthogonal
acceleration time-of-flight (oa-Tof) instrument.
