High throughput screening of high-affinity ligands for proteins with anion-binding sites using desorption electrospray ionization (DESI) mass spectrometry.
Article in Journal of the American Society for Mass Spectrometry, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
A high throughput screening system involving a linear ion trap (LTQ) analyzer, a house-made platform and a desorption electrospray ionization (DESI) source was established to screen ligands with a high affinity for proteins with anion-binding sites. The complexes were analyzed after incubation, ultrafiltration, washing, and displacement. A new anionic region inhibited dissociation (ARID) mechanism that was suitable for a protein with anion-binding site was proposed. We utilized the differences in detectable dissociation of protein-ligand complexes, combined with displacement experiments, to distinguish free ligands displaced from anion-binding sites from liberated ligands dissociated from nonspecific interactions. The method was validated by α1-acid glycoprotein (AGP) and (R), (S)-amlodipine. Site-specific enantioselectivity shown in our experiments was consistent with earlier studies. Obtaining all of the qualitative information of 15*3 samples in 2.3 min indicates that the analysis process is no longer the time-limiting step in the initial stage of drug discovery. Quantitative information verified that our method was at least a semiquantitative method.
