A Novel Method to Isolate RNase MRP Using RNA Streptavidin Aptamer Tags.

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
Interactions between RNA-binding proteins and RNA molecules are at the center of multiple biological processes. Therefore, accurate characterization of the composition of ribonucleoprotein complexes (RNPs) is crucial. Ribonuclease (RNase) for mitochondrial RNA processing (MRP) and RNase P are highly similar RNPs that play distinct roles at the cellular level; as a consequence, the specific isolation of either of these complexes is essential to study their biochemical function. Since their protein components are nearly identical, purification of these endoribonucleases using protein-centric methods is not feasible. Here, we describe a procedure employing an optimized high-affinity streptavidin-binding RNA aptamer, termed S1m, to purify RNase MRP free of RNase P. This report details all steps from the RNA tagging to the characterization of the purified material. We show that using the S1m tag allows efficient isolation of active RNase MRP.
