Characterization of Small Molecule-Protein Interactions Using SPR Method.
Article in Methods in molecular biology (Clifton, N.J.), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Surface plasmon resonance (SPR) is an optical phenomenon being used to monitor molecular binding events. With the advantages of being label-free, real-time, and sensitive, SPR assays have become one of the most commonly used techniques to measure binding kinetics, affinity, specificity, and concentration of molecular interactions. In an SPR experiment to measure small molecule-protein interactions, the protein is immobilized on the biosensor surface, while the small molecule flows through the surface of the sensor chip. The interactions between the small molecules and proteins are monitored by subsequent changes in the refractive index and quantified with resonance units. In this chapter, we have utilized an SPR assay to study the interaction of flavonoids and the glucose-regulated protein 78. Assay steps are detailed for immobilization optimization, SPR instrument setup, operation, sample injection, and affinity data analysis.
