Improvements for Tissue-Chopping-Based Immunofluorescence Staining Method of Chloroplast Proteins.

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
Immunofluorescence staining is a very common method for the subcellular localization study of proteins. A tissue-chopping-based immunofluorescence staining method for chloroplast proteins overcomes the restriction of plant cell wall, makes the operation simpler, and uses less experimental materials. Here we provide some improvements for this method. We found that the stained tissues can be directly observed with a confocal microscope without tissue lysis. Samples maintained at a low temperature (0-4 °C) throughout the process can reduce the intensity of chlorophyll autofluorescence and the background signal. A low temperature is also good for the storage of the sample. Fluorescence signal of the stained samples can be kept for several weeks if they are stored at -20 °C. FtsZ is an essential component of the chloroplast division apparatus. We demonstrated this method with the immunofluorescence staining of FtsZ1 in wildtype Arabidopsis and some chloroplast division mutants. We also successfully tested this method by the immunofluorescence staining of FtsZ1 in many other plants, including woody plants. With these procedures, the performance of tissue-chopping-based immunofluorescence staining method are further improved.
