TECHNICAL NOTE Speed: Opera Phenix Plus high-content screening system technical performance. As shown by an analysis of HCS-related publications, the number of high-content screens being run each year continues to increase, however a large number of screens are not as “high-content” as they could be (Singh et al. 2014). The majority of high-content screens described in published papers rely on only 1-2 image-based features rather than multi-parametric results for single cells. This is indicative of more target-based approaches being used in drug screening. In very recent times, there is evidence of a reversal towards more phenotypic based screens. Prior to this, reasons for the limited adoption of phenotypic screening approaches might have included insufficient hardware but also the lack of suitable software to analyze complex phenotypes (see also Roberts and Tesdorpf 2015). The Opera Phenix® Plus high-content screening system has been specifically developed to enable users to perform highly multi-parametric phenotypic screens effectively. Authors Angelika Foitzik Ruben Prange Karin Böttcher Alexander Schreiner Revvity, Inc. Waltham, MA The Opera Phenix Plus combines state of the art hardware to allow simultaneous acquisition of up to four fluorescent channels, with Harmony® high-content imaging and analysis software for convenient experimental set-up and analysis. The following table summarizes the new features and main improvements of the Opera Phenix Plus system and explains how they benefit acquisition and analysis speed. For research use only. Not for use in diagnostic proced

This leads to shorter exposure times, higher the high numerical aperture of water immersion objectives resolution, less photo bleaching and improved 3D imaging. increases the acquisition speed dramatically. Using a water A further increase in acquisition speed can be achieved by immersion objective lens instead of an air lens reduces the exposure time about 5-fold, due to its better light collecting Figure 1.Speed improvement in a...

This requires less a third of the time. This can be explained by the larger field overhead for loading and decompressing of images during of view of the sCMOS camera, leading to a data set that only Acapella is the high-content imaging and analysis software for the Opera QEHS high-content screening system, which is no longer commercially available. * Figure 4.
