1 · What the graph read from it

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.

2 · The registry

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

We have developed a series of plasmid vectors for the soluble expression and subsequent purification of recombinant proteins that have historically proven to be extremely difficult to purify from Escherichia coli. Instead of dramatically overproducing the target protein, it is expressed at a low basal level that facilitates the correct folding of the recombinant protein and increases its solubility. Highly active recombinant proteins that are traditionally difficult to purify are readily purified using standard affinity tags and conventional chromatography. To demonstrate the utility of these vectors, we have expressed and purified full-length human DNA polymerases η, ι, and ν from E. coli and show that the purified DNA polymerases are catalytically active in vitro.
