Retention Time Windows: Why ±0.05 Minutes Is the Sweet Spot for Background Hit Filtering
Virscidian's analysis of a high-throughput AS-MS screen revealed that setting retention time windows to ±0.05 minutes optimally balances filtering true background cross-hits—capturing over 99% of them—while minimizing false positives from isomeric peaks, making this the recommended threshold for automated cross-hit filtering in workflows like Analytical Studio.
Reducing False Positives from Isotopic Misidentification in AS-MS
Enabling automated X–1 and X–2 isotopic misidentification filters in affinity selection-mass spectrometry (AS-MS) reduces false positive compound hits by 5% by preventing misassignment of isotopic peaks (e.g., M+1 or M+2) as distinct compounds, thereby improving hit list accuracy.
Affinity Selection-Mass Spectrometry with Kd Analysis Overview
The document explains that Kd, the ligand concentration at which half of a protein's binding sites are occupied, is a crucial measure of binding affinity in drug discovery, and describes how Analytical Studio uses Affinity Selection-Mass Spectrometry (AS-MS) to semi-quantitatively determine apparent Kd values by generating dose response curves from mass spectrometry data, with features including customizable data displays and automated Kd calculations to facilitate efficient analysis and candidate ranking.
Limitations of Existing Life Science Software—and the Opportunity to Evolve
