Measuring Partition Coefficients of In Vitro Biomolecular Condensates Using Fluorescence Correlation Spectroscopy.

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
Liquid-liquid phase separation is a widespread organizing principle of live cells, including, for example, the spatiotemporal organization of bacterial chromatin. The biophysics of phase-separating systems is often studied in vitro to avoid the complexity of the live-cell environment and facilitate application of advanced biophysical methods. One attractive method for measuring, e.g., partition coefficients, in such systems is fluorescence correlation spectroscopy (FCS). FCS circumvents some of the limitations of the widespread confocal laser scanning microscopy image-based measurements. Here, we describe how to perform partition coefficient measurements in biological phase-separating systems. Our protocol details typical workflows for the preparation of in vitro reconstituted condensates, FCS data acquisition, and subsequent data analysis, including corrections of some common artifacts. Our recommendations should help avoid many pitfalls of partition coefficient determination in these challenging systems.
