High-accuracy molecular mass determination of proteins using matrix-assisted laser desorption mass spectrometry
Abstract
A method for obtaining protein molecular masses with an accuracy of approximately +/- 0.01% by matrix-assisted laser desorption using an internal calibrant is described. The technique allows accurate mass determinations of protein sample sizes as small as 1 pmol. High concentrations of organic and inorganic contaminants (e.g. 1 M urea) do not strongly affect either the signal intensity or the mass assignment. The ability to assign an accurate molecular mass to a protein is contingent on the observation of clearly resolved protonated molecule ions in the mass spectrum.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
