Expression and purification of MERS-CoV envelope protein, an essential viroporin, using the baculovirus expression system.

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
Background and Objectives: The causative agent of Middle East Respiratory Syndrome (MERS) is a zoonotic Coronavirus (MERS-CoV) identified in Saudi Arabia in 2012. The envelope (E) protein of MERS-CoV is a small viral protein which plays several essential roles during virus replication. To facilitate study of the structure and function of the E protein, recombinant MERS-CoV E protein was expressed using the baculovirus expression system. Materials and Methods: A recombinant E open reading frame including an 8-histidine tag at the amino terminus was designed and cloned into a baculovirus transfer vector. Following construction of a recombinant virus insect cells were infected and the expression of the E protein assessed by SDS-PAGE and Western blotting. Results: Recombinant E protein, tagged at the N-terminus with a polyhistidine sequence, with a molecular mass of 10.18 kD was identified by Western blotting with an anti-His antibody. Following large scale infection E protein was released by detergent mediated lysis of infected cells and purified by Immobilized Metal Ion Affinity Chromatography (IMAC). Conclusion: Purified full length recombinant MERS-CoV E protein can be isolated by IMAC and is suitable for further functional, biophysical or immunological studies.
