Sentence examples for quantitation based on from inspiring English sources
Though mass spectrometric analyses of this type are not fully quantitative, recent studies have established that relative quantitation based on the signal strength of permethylated glycans analyzed by MALDI-TOF MS is indeed both possible and accurate, especially when comparisons are carried out among related species across small mass ranges (Wada et al. 2007).
An advantage of this labeling approach is the stoichiometric attachment of one label per glycan, allowing a direct quantitation based on fluorescence or UV-absorbance intensity.
The exploration of spectral counting quantitation based on LC-MS presented here gathers experimental evidence of the influence of batch effects on comparative proteomics.
The label-free quantitation based on peptide-spectral counts offers a high-coverage identification of proteins, and then gives a comprehensive and rapid comparison to the differential proteins, especially to the plasma proteins [48].
For each mouse brain the spectrum of the relative amount of metabolites inside the experimental PRESS volume was quantified using the QUEST (quantitation based on quantum estimation) module [124] available inside the Java Magnetic Resonance User Interface (JMRUI) package [125].
The described approach to protein quantitation, based on the use of an exogenous IRS that is co-extracted by a multiplexed antibody system, has been previously discussed [22], [23], however, this is the first report of such an approach in the quantitative measurement of RBP4.
In the analog methods, standard curves are necessary for quantitation, because the quantitation is based on an assay signal, or output, not counting.
The calculations were performed by the AlleleSEQR Quantitation Software based on the relative quantitation method (2-ΔΔCT).
The mass spectrometer operated for quantitative analysis in full scan MS/MS and quantitation was based on post processing MRM extracted ion chromatograms.
Quantitation is based on a spectral fit that uses previously determined infrared molecular line parameters generated in our laboratory, including line positions, line strengths and nitrogen-broadened half-widths for these species.
Quantitation was based on a gallic acid standard calibration curve.
