Extracellular signal-regulated kinase (ERK) is a key component in the regulation of embryogenesis, cell differentiation, cell proliferation, and cell death. The ERK signaling pathway is altered in various cancer types and is frequently investigated as a target for therapeutic intervention. This application note describes how a live cell FRET assay to study ERK signaling was performed on the Operetta CLS™ high-content analysis system. The optimized design of the FRET-based biosensor, the high-quality imaging of the Operetta CLS system and the easy-to-use image analysis tools of the Harmony® software contribute to the robustness of the high-content assay.
In this application note, we describe a high-content screening application for analyzing the migration of non-small cell lung cancer cells in a live cell assay. Using the Operetta® high-content imaging system and digital phase contrast imaging, we tracked migrating cancer cells using automated single cell tracking in the Harmony® high-content imaging and analysis software.
The promise of high-content screening is the acceleration of discovery by extracting as much relevant information as possible from cells. Nevertheless, a large percentage of high-content screens analyze only a small number of image-based properties. As a result, valuable information from precious cells and disease models is not utilized. As nearly all screening approaches require a nuclear counterstain such as Hoechst to facilitate segmentation, phenotypic profiling of the nuclei can offer new and additional perspectives on assays at no extra cost.

Learn how: The Opera Phenix system has been applied in the field of neurodegenerative diseases. In this assay, the Opera Phenix system is 4 times faster than the previous Opera® system. Primary neuron morphology is analyzed in a straightforward approach using Harmony software. Careful assay optimization can increase throughput, and minimize the data burden, without compromising assay performance.

One of the greatest challenges in multiple sclerosis (MS) therapy is the halting or reversal of the failure of remyelination in the brain in order to reverse disabilities in MS patients. This case study highlights the recent work of Dr. Paul Tesar and colleagues at the Case Western Reserve University School of Medicine, which could potentially lead to such novel treatments, as it aims to control the function of stem cells in the body and thereby to help the body repair itself.

Whether you’re familiar with high-content screening, or a newcomer, you’ll need the right tools and strategies to overcome the challenges of using complex 3D cell models in such an assay. For example, growing consistent, reproducible 3D cultures can be problematic and imaging large, thick cell samples can be challenging, while managing the huge volumes of data generated is perhaps the most demanding aspect of all. In this article, we provide our top tips for running a successful high-content screening assay using a 3D cell model. Learn how you can: Generate uniform 3D cell models, Get the best quality images, Minimize imaging time and volume of data, Get deeper insights from your 3D cell model and Avoid unnecessary data transfer steps.
High-content assays using 3D objects such as cysts or organoids can be challenging from the perspectives of both image acquisition and image analysis. In this technical note we describe how to image and analyze epithelial Madin-Darby canine kidney (MDCK) cysts in 3D on the Operetta CLS™ high-content analysis system.
Multicellular 3D “oids” (tumoroids, spheroids, organoids) have the potential to better predict the effects of drug candidates during preclinical screening. However, compared to 2D cell monolayers, assays using 3D model systems are more challenging.
In this technical note we describe how to image and analyze solid spheroids in 3D using the Opera Phenix™and Operetta™CLS high-content screening systems and Harmony® 4.8 imaging and analysis software.
In drug discovery programs, multicellular spheroids have emerged as powerful tools to bridge the gap between in vitro cell culture models and in vivo tissues. However, one of the greatest challenges in higher throughput 3D imaging is the acquisition of images of solid spheroids, owing to the reduced light penetration.
One solution is to use optical clearing techniques, which can enhance the imaging depth in spheroids by removing lipid and protein molecules.
In this technical note, we compare different optical clearing strategies for 3D spheroids and quantify the clearing effectiveness and alterations in spheroid morphology, and demonstrate how to increase imaging depth in 3D spheroids by a factor of four.
Live cell imaging has gained importance within drug discovery over recent times, as researchers look for more meaningful insights into cellular behavior and function.

Spinning disk confocal microscopy is a common tool for live cell microscopy and reduces background fluorescence from out of focus planes. However, for 3D imaging, confocal image quality can be limited by a phenomenon known as ‘pinhole crosstalk’ which can lead to blurred images in conventional spinning disk systems. The confocal scanning unit of the Opera Phenix™ High-Content Screening System provides an increased distance between pinholes to reduce the pinhole crosstalk, leading to improved 3D image quality. Learn more in our Technical Note.
Balancing the key factors in HCS imaging - sensitivity, resolution and speed - can be challenging since they cannot be optimized independently: changing one impacts the others. Nevertheless, there is a way to overcome some of the obstacles and here we explain why the choice of the objective lens is critical.
The key parameters in high-content imaging - speed, sensitivity (or intensity) and resolution - cannot be optimized independently as altering one of them influences the others. For example, increasing the resolution by choosing a higher magnification requires imaging of more fields to maintain the same cell number – at the expense of speed; or increasing the fluorescence intensity can be achieved by increasing the exposure time – again at the expense of speed. Nevertheless, there is a way to overcome some of these obstacles and here, in this Technical Note, we explain why the choice of the objective lens is critical.
