Sentence examples for maximum mass deviation from inspiring English sources

Stringent acceptance criteria were applied, which included maximum mass deviation of the precursor ion of 5 ppm, and rejection of peptides shorter than seven amino acids.

Peptides precursor ions were searched with a maximum mass deviation of 10 p.p.m. and fragment ions with a maximum mass deviation of 1 Da.

In analogy to our previous work (Römpp et al. 2007), a maximum mass deviation of 3 ppm between m/ z values of MALDI imaging peaks and masses of peptides identified by LC ESI MS/MS was accepted in this study.

The terms 'mass deviation,'massss accuracy' and 'maximum mass deviation' are used according to the definition by Zubarev and Mann (2007).

For annotation of the molecular formula of precursor ions, the maximum tolerated mass deviation was set to ±3 ppm.

To investigate whether the 98 unidentified 8-plex peptides were possibly present in the sample and were fragmented at all, we searched the data again using much less stringent criteria (minimum Mascot Score 1, minimum peptide length 8, maximum peptide mass deviation 8 ppm) in an attempt to increase sensitivity.

98 peptides were not detected in any of the four 8-plex analyses applying our stringent search criteria (Mascot ions score threshold 20, rank 1, Mascot significance threshold 0.05, minimum peptide length 8, maximum peptide mass deviation 8 ppm) that ensured false discovery rates less than 1% on both the peptide and protein levels in all analyses.

Then, all such detected M and M′ pairs from different scans are combined with hierarchical clustering using the assigned number of heavy isotopes per metabolite ion and the m/ z value of M. Clusters showing a maximum relative mass deviation between their highest and lowest m/ z value of less than a preset threshold in parts per million are not further split.

A maximum of one missed cleavage, mass deviation of 20 ppm and 0.1 Da were allowed for MS and MS/MS, respectively.

Fig. 1 Number of molecular formulas that match the mass of some precursor peak in the Agilent and GNPS dataset, using the maximum of 10 ppm and 2 mDa as allowed mass deviation.

In the pine specimens, C. puteana reached a maximum mass loss (50%) after 6 weeks (however, the standard deviation was high), yet energy production continually increased from 6 to 12 weeks of incubation (Fig.  6c,d).
