Identification of DAPs using TMT-based quantitative proteomics analysis Using the criterion of fold change > 1.2 or < 1/1.2 (0.8333) andP-value < 0.05, a total of 518 DAPs were screened in A vs. B, with 258 up-regulated and 260 down-regulated proteins under control condition; 214 up-...
4、进行TMT、iTRAQ蛋白组学研究时,isolation interference值最好设在30%以下。 参考文献 Sandberg A, Branca RM, Lehtiö J, Forshed J. Quantitative accuracy in mass spectrometry based proteomics of complex samples: the impact of labeling and precursor interference. J Proteomics. 2014...
Using high-resolution mass spectrometry-based quantitative proteomics of the bovine whey proteins, we identified a total of 1459 and 1358 proteins in biological replicates, out of which 220 and 157 proteins were differentially expressed between normal and infected samples. A total of 82 proteins were...
The principle of TMT based proteomics In MS1 spectrum, the same peptide segment from different labeled samples showed a peak, due to the same peptide segment in different samples labeled by TMT reagent showed the same mass-to-charge ratio. ...
