Quantitative mass spectrometric multiple reaction monitoring assays for major plasma proteins.
Quantitative LC-MS/MS assays were designed for tryptic peptides representing 53 high and medium abundance proteins in human plasma using a multiplexed multiple reaction monitoring (MRM) approach. Of these, 47 produced acceptable quantitative data, demonstrating within-run coefficients of variation (CVs) (n = 10) of 2-22% (78% of assays had CV <10%). A number of peptides gave CVs in the range 2-...
متن کاملCombinatorial peptide libraries facilitate development of multiple reaction monitoring assays for low-abundance proteins.
Low-abundance proteins present in biological fluids are often considered an attractive source of new disease biomarkers. Since such proteins are poorly observed in proteome-scale discovery experiments due to an overwhelming mass of high-abundance proteins, the development of quantitative multiple reaction monitoring (MRM) assays for low-abundance proteins is a challenging task. Here, we present...
متن کاملMass spectrometric detection of tissue proteins in plasma.
It has long been thought that blood plasma could serve as a window into the state of one's organs in health and disease because tissue-derived proteins represent a significant fraction of the plasma proteome. Although substantial technical progress has been made toward the goal of comprehensively analyzing the blood plasma proteome, the basic assumption that proteins derived from a variety of t...
متن کاملQuantitative performance of internal standard platforms for absolute protein quantification using multiple reaction monitoring-mass spectrometry.
Stable-isotope-labeling mass spectrometry involves the addition of known quantities of stable-isotope labeled standards, which mimic native molecules, to biological samples. We evaluated three conventional internal standard platforms (synthetic peptides, QconCAT constructs, and recombinant proteins) for quantitative accuracy, precision, and inherent advantages and limitations. Internal standard...
متن کاملTargeted Selected Reaction Monitoring Mass Spectrometric Immunoassay for Insulin-like Growth Factor 1
Insulin-like growth factor 1 (IGF1) is an important biomarker of human growth disorders that is routinely analyzed in clinical laboratories. Mass spectrometry-based workflows offer a viable alternative to standard IGF1 immunoassays, which utilize various pre-analytical preparation strategies. In this work we developed an assay that incorporates a novel sample preparation method for dissociating...
