A solvent-free delipidation method for functional validation of lipases.

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
Extracting protein in its active form is critical for its functional characterization, and lipid removal is an essential step in the protein extraction process for further downstream applications. In the present study, we revisited the delipidation protocol and developed a rapid, solvent-free delipidation method using activated silica. The delipidated samples showed improved optical clarity and a significant reduction of endogenous lipids. The functional integrity of the lipases present in the delipidated sample was validated by in vitro enzyme assay using physiological substrate which includes neutral lipid as well as phospholipid. The accessibility of active site of the extracted enzymes was demonstrated by activity-based protein profiling (ABPP), a functional chemoproteomic approach. Detection of serine hydrolases using ABPP probe labeling was enhanced upon delipidation. Further, the total polyphenol content was significantly reduced, which helps to enhance the protein enrichment and small-molecule inhibitor screening by ABPP. Collectively, these results suggest that the present solvent-free delipidation approach is efficient and highly compatible with the functional characterization of the enzymes, particularly lipid hydrolases.
