3D midbrain organoid model development

The drug development path—from hit discovery to the clinical space—relies on accurate experimental data that are predictive of outcomes in downstream settings. Increasing the complexity of disease models with 3D organoids in the early stages of drug discovery is an approach that provides a more relevant cellular context and potentially more accurate physiological data in orthogonal experiments. The development of 3D organoids that better represent the corresponding organ complexity enables researchers to better scale experiments, make data-driven decisions, and systemize those processes to speed discovery.

On-demand webinar: Strategies for isolation of plasma membrane proteins

Isolating plasma membrane proteins presents many challenges, and it can often prove difficult to choose the right method based on the sample and downstream application. This webinar focuses on robust and optimized techniques for extraction, isolation, and enrichment of cell-surface proteins, including stable and functional G protein–coupled receptors (GPCRs). In this webinar, we present:

• Techniques for isolating plasma membrane proteins
• Ways to produce stable and functional GPCR extracts
• Enrichment methods for cell-surface proteins that produce minimal off-target contaminants
• How cell-surface proteins can serve as a treasure trove of pharma-relevant targets for potential drug therapy

Updated: The Attune NxT Flow Cytometer reference article database

Scientists at Thermo Fisher Scientific have established a reference article database that features over 475 peer-reviewed publications citing the use of the Invitrogen Attune NxT Flow Cytometer. You can easily perform keyword searches (e.g., author, cell type, species) to access hundreds of articles in various areas of life science research, from immunology, immunotherapy, cancer, and drug discovery, to food, agriculture, and veterinary and materials sciences. It includes scientific articles published through 2019, and we are committed to updating it with new references as they are published. Learn more about how the Attune NxT Flow Cytometer can enhance your research with its ability to provide consistent results, whether samples are dilute or concentrated, require fast or slow flow rates, or are susceptible to clogging during analysis.

Best practices: 5 steps to intracellular flow cytometry

The ability to detect intracellular proteins with flow cytometry opens the door to a more complete characterization of cell populations and distinct subsets within those populations. To help you save time and effort and increase your efficiency when designing flow cytometry experiments, we have organized our resources, tools, and products for intracellular flow cytometry into 5 simple steps:

• Step 1: Target determination, with a link to our antibody search tool
• Step 2: Buffer selection, with fixation and permeabilization buffers for cytoplasmic and nuclear staining
• Step 3: Panel design, with online tools to create a customized panel and search published multicolor flow cytometry panels
• Step 4: Biological controls, with a product selection guide that contains fluorescent cell stains for removing dead cells and unwanted artifacts from your analysis
• Step 5: Experimental controls, with products to facilitate antibody compensation controls
