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 and implemented an in vitro compartmentalization (IVC) selection scheme for the identification of streptavidin (SA) variants with altered specificities for the biotin analog desthiobiotin. Wild-type SA and selected variants bind desthiobiotin with similar affinities (approximately 10(-13) M), but the variants have off rates almost 50 times slower and a half-life for dissociation of 24 hr at 25 degrees C. The utility of streptavidin variants with altered specificities and kinetic properties was shown by constructing protein microarrays that could be used to differentially organize and immobilize DNAs bearing these ligands. The methods we have developed should prove to be generally useful for generating a variety of novel SA reagents and for evolving other extremely high-affinity protein:ligand couples.
