Synchronous Precursor Selection (SPS) enables improved specificity, significantly increasing analytical performance of TMT-based quantification experiments. Applying Real-Time Search data acquisition strategy with the SPS MS3 method enables the comprehensive characterization of at least 10-plex proteome in 50% less acquisition time by leveraging the MS2 spectrum and Real-Time Search data acquisition to determine which precursors are further analyzed by SPS MS3, increasing the efficiency and confidence of data acquisition. Data indicates that the Real-Time Search-aided TMT SPS MS3 workflow provides dramatic performance improvements for quantitative multiplexed experiments.*

Real Time Search Greater Depth Quantitative Accuracy

Real-Time Search data acquisition improves experimental speed and quantitation accuracy

Real-Time Search improves experimental speed and quantification accuracy when combined with the advanced SPS MS3 experimental approach. With Real-Time Search data acquisition, MS3 scans are only triggered if a peptide-spectrum match (PSM) is identified from the preceding MS2. This reduces the number of MS3 events, increases the precursor sampling rate and results in a greater number of quantified peptides; improving experimental speed. With the aid of the Real-Time Search data acquisition strategy, the Orbitrap Eclipse Tribrid MS selects only those fragment ions that correspond to the identified PSM for quantification in the MS3 scan, resulting in improved quantitation accuracy.

Thermo Scientific SureQuant IS Targeted Protein Quantitation workflow is a data-aware quantitation scan mode leveraging internal standards to dynamically adjust scan parameters and automatically maximize data quality for targeted proteome analysis in real time. The SureQuant method fills the gap for large-scale target profiling with superior quantitative performance.

Validation of protein state in molecular biology experiments needed

SureQuant IS targeted protein quantitation

While triple quadrupole-based Selected Reaction Monitoring (SRM) and high-resolution Parallel Reaction Monitoring (PRM) approaches are different, each offers advantages to targeted quantitation. SureQuant IS targeted protein quantitation with Thermo Scientific Orbitrap mass analyzer-based mass spectrometry reduces the inevitable trade-off between target multiplexing, sensitivity and selectivity. This method enlarges targeted protein panel sizes and significantly improves limits of detection (LODs) and quantitative accuracy without use of retention time windows.

SureQuant targeted protein quantitation

SureQuant method facilitates an intelligence-driven approach

SureQuant method target detection occurs independently of Retention Time (RT) scheduling, allowing reliable and robust target quantification. This intelligence-driven approach for quantitation enables self-adjustment for higher sensitivity without compromising cycle time.
