美利体育登录入口官网:使用TMT和PQD对蛋白酶解物进行相对定量
简介：
To demonstrate the benefits of the PQD-based quantitation of isobarically labeled peptides in protein digests.
仪器：
LTQ XL
结论：
• Optimization of PQD parameters for LC MS/MS analysis is important for reproducible and accurate protein quantitation.
• The PQD fragmentation technique produces high quality MS/MS spectra with good signal to noise for TMT reporter ions.
• The accuracy of the TMT ratios was better than 19% on the protein level.
• Proteome Discoverer performs protein identification and protein quantitation using the MS/MS spectra generated by PQD. Reporter ion intensities of the MS/MS spectra were successfully used for peptide and protein quantitation.
