Optimized In-Solution and Gas-Phase Chemistry Enables High-Efficiency Interactome Mapping by DSBSO-Based Cross-Linking Mass Spectrometry.
Article in Angewandte Chemie (International ed. in English), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cross-linking mass spectrometry (XL-MS) allows characterizing protein structures and interactions in highly complex samples. The enrichable disuccinimidyl bissulfoxide (DSBSO) cross-linker has enabled comprehensive XL-MS studies of human cells. However, existing DSBSO workflows demand multi-day sample preparation with high input requirements and provide insufficient detection sensitivity. Here, we systematically optimize the in solution and gas-phase chemistry of azide-A-DSBSO-based XL-MS. Importantly, we reduce sample preparation time to 10 h and introduce StageTip-based strong cation exchange (SCX) separation to concomitantly remove nonvolatile salts and interfering contaminants. Applying our streamlined SCX protocol to intact Bacillus subtilis reduced sample consumption 15-fold compared to conventional size-exclusion chromatography-based azide-A-DSBSO XL-MS and doubled the identification numbers, yielding 3,209 protein interactions at a 1% false-discovery rate. These results illustrate that our optimized workflow unites speed, analytical depth, and resource efficiency, making XL-MS amenable to high-throughput interactome profiling of complex biological samples.
