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

A method is presented to assemble a gene of interest into a linear DNA template with all the components necessary for in vitro transcription and translation in approximately 90 min. Assembly is achieved using a coupled uracil excision-ligation strategy based on USER Enzyme and T4 DNA ligase, which allows the simultaneous and seamless assembly of three different PCR products. The method is suitable for screening and selection systems of very high throughput as up to 10(11) molecules can be efficiently assembled and purified in reaction volumes of 100 microl. The method is exemplified with the gene coding for a mutant version of O(6)-alkylguanine alkyltransferase, which is efficiently assembled with an N-terminal peptide tag and its 5'- and 3'-untranslated regions that include a T7 promoter, ribosome binding site and T7 terminator. The utility of the method is further corroborated by assembling error-prone PCR libraries and regenerating templates following model affinity selections. This fast and robust method should find widespread application in directed evolution for the assembly of gene libraries and the regeneration of linear DNA templates between successive screening and selection cycles.
