The purpose of this study was to generate a basis for the decision of what protein quantities are reliable and find a way for accurate and precise protein quantification. To investigate this we have used thousands of peptide measurements to estimate variance and bias for quantification by iTRAQ (iso...
We performed a high throughput comparative proteomics study to identify differentially expressed proteins that could serve as putative targets in retinoblastoma. We used iTRAQ based quantitative proteomics approach and analyzed the samples on orbitrap velos mass spectrometer. We identified and quant...
Stable VPS35 knockdown HeLa cells were generated using lentiviral short hairpin RNA (shRNA) construct. Isobaric tags for relative and absolute quantitation (iTRAQ)-based mass spectrometry was used to measure the changes of nuclear protein abundance in VPS35-depleted HeLa cells.
