Related to Mass spectra:mass spectrometry mass spectrum n. A pattern of charged atoms, molecules, or isotopes formed when a mass spectroscope distributes them by mass and records them electronically or photographically as a spectrum.

In addition, it is known that the heterogeneity of tumour tissues and possible carcinoma infiltration increase the variability of spectral data collected from tissues. Therefore, it is necessary to collect a large number of spectra from each tissue sample to better represent the data, but this may...
Accession number. The mass spectrometry proteomics data have been deposited to the ProteomeXchange Consortium40 via the PRIDE partner repository with the dataset identifier PXD001646. Results and Discussion UNID- and ID-consensus spectral libraries. A total of 1,188,790 MS/MS spectra were ...
NAD(P)H had a higher two-photon excitation action cross-section at shorter wavelengths94, this was the excitation-emission setting (755 nm ex./460 nm em.) that was used in our previous studies that validated optical redox ratio estimates to corresponding mass spectrometry ones13,14. At the ...
acquired in the ion trap mass analyser. MS2 spectra were searched in real time with data acquisition using the PHROG database52with added mitochondrially encoded proteins. Identified MS2 spectra triggered the submission of MS3 spectra that were collected using the multinotch MS3-based TMT method53...
(A)+RNA from labeled cells, prop6A was unambiguously detected, whereas it was not detectable in control cells (Fig.2i). It replaced 3.5% of m6A (Fig.2h) and was present in 0.0023% of all As (Fig.2i). Taken together, these data indicate that PSH can be used for metabolic labeling...
Using data dependent acquisition, 10 multiply charged ions with intensities above the absolute threshold of 25,000 were automatically selected for fragmentation. The target mass was set on 1,200 m/z. MS analysis was performed in the positive ion mode within mass range 400–1,500 m/z ...
Orbital-free density functional theory (OFDFT) is a quantum chemistry formulation that has a lower cost scaling than the prevailing Kohn–Sham DFT, which is increasingly desired for contemporary molecular research. However, its accuracy is limited by the
(77 K) fluorescence emission spectra of the three fractions indicated inb. The excitation wavelength was 580 nm ind,e. All the spectra were normalized based on their maximal values.fSDS-PAGE of fraction Ap-3 stained with Coomassie Blue G-250. Protein mass standards (kDa) are indicated ...
