The superiority and feasibility of 2,3,5-triphenyltetrazolium chloride-stained brain tissues for molecular biology experiments based on microglial properties.

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
backgroundTTC (2,3,5-triphenyltetrazolium chloride) staining is the most commonly used method in identifying and assessing cerebral infarct volumes in the transient middle cerebral artery occlusion model. Given that microglia exhibit different morphologies in different regions after ischemic stroke, we demonstrate the superiority and necessity of using TTC-stained brain tissue to analyze the expression of various proteins or genes in different regions based on microglia character.
methodsWe compared brain tissue (left for 10 min on ice) from the improved TTC staining method with penumbra from the traditional sampling method. We identified the feasibility and necessity of the improved staining method using real time (RT)-PCR, Western blot, and immunofluorescence analysis.
resultsThere was no protein and RNA degradation in the TTC-stained brain tissue group. However, the TREM2 specifically expressed on the microglia showed a significant difference between two groups in the penumbra region.
conclusionsTTC-stained brain tissue can be used for molecular biology experiments without any restrictions. In addition, TTC-stained brain tissue shows greater superiority due to its precise positioning.
