Expression and purification of recombinant vesicular glutamate transporter VGLUT1 using PC12 cells and High Five insect cells.

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
In synaptic vesicles, the estimated concentration of the excitatory amino acid glutamate is 100-150 mM. It was recently discovered that VGLUT1, previously characterized as an inorganic phosphate transporter (BNPI) with 9-11 predicted transmembrane spanning domains, is capable of transporting glutamate. The expression and His-tag based purification of recombinant VGLUT1 from PC12 cells and High Five insect cells is described. Significantly better virus and protein expression was obtained using High Five rather than Sf9 insect cells. PC12 cell expressed VGLUT1 is functional but not the Baculovirus expressed protein. The lack of functionality of the Baculovirus expressed VGLUT1 is discussed. The data indicate that VGLUT1 readily oligomerizes/dimerizes. The data are discussed in the context of developing this system further in order to reconstitute vesicular glutamate uptake in vitro using lipid-detergent vesicles.
