Characterization of Adeno-Associated Virus Capsid Proteins by Microflow Liquid Chromatography Coupled with Mass Spectrometry.

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
Adeno-associated virus (AAV) has been widely used to treat various human diseases as an important delivery vector for gene therapy due to its low immunogenicity and safety. AAV capsids proteins are comprised of three capsid viral proteins (VP; VP1, VP2, VP3). The capsid proteins play a key role in viral vector infectivity and transduction efficiency. To ensure the safety and efficacy of AAV gene therapy products, the quality of AAV vector capsid proteins during development and production should be carefully monitored and controlled. Microflow liquid chromatography coupled with mass spectrometry provides superior sensitivity and fast analysis capability. It showed significant advantages in the analysis of low- concentration and large numbers of AAV samples. The intact mass of capsid protein can be accurately determined using high-resolution mass spectrometry (MS). And MS also provides highly confident confirmation of sequence coverage and post-translational modifications site identification and quantitation. In this study, we used microflow liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the characterization of AAV2 capsid protein. we obtained nearly 100% sequence coverage of low-concentration AAV2 capsid protein (8 × 10
