Rapid and efficient purification of RNA-binding proteins: application to HIV-1 Rev.
Article in Protein expression and purification, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Non-specifically bound nucleic acid contaminants are an unwanted feature of recombinant RNA-binding proteins purified from Escherichia coli (E. coli). Removal of these contaminants represents an important step for the proteins' application in several biological assays and structural studies. The method described in this paper is a one-step protocol which is effective at removing tightly bound nucleic acids from overexpressed tagged HIV-1 Rev in E. coli. We combined affinity chromatography under denaturing conditions with subsequent on-column refolding, to prevent self-association of Rev while removing the nucleic acid contaminants from the end product. We compare this purification method with an established, multi-step protocol involving precipitation with polyethyleneimine (PEI). As our tailored protocol requires only one-step to simultaneously purify tagged proteins and eliminate bound cellular RNA and DNA, it represents a substantial advantage in time, effort, and expense.
