Multicolor Microscopy: The Importance of Multiplexing

The term multiplexing refers to the use of multiple fluorescent dyes to examine various elements within a sample. Multiplexing allows related components and processes to be observed in parallel,…

A New Method for Convenient and Efficient Multicolor Imaging

The technique combining hyperspectral unmixing and phasor analysis was developed to simplify the process of getting images from a sample labeled with multiple fluorophores. This aggregate method…

Considerations for Multiplex Live Cell Imaging

Simultaneous multicolor imaging for successful experiments: Live-cell imaging experiments are key to understand dynamic processes. They allow us to visually record cells in their living state, without…

High-resolution 3D Imaging to Investigate Tissue Ageing

Award-winning researcher Dr. Anjali Kusumbe demonstrates age-related changes in vascular microenvironments through single-cell resolution 3D imaging of young and aged organs.

Optimizing THUNDER Platform for High-Content Slide Scanning

With rising demand for full-tissue imaging and the need for FL signal quantitation in diverse biological specimens, the limits on HC imaging technology are tested, while user trainability and…

Physiology Image Gallery

Physiology is about the processes and functions within a living organism. Research in physiology focuses on the activities and functions of an organism’s organs, tissues, or cells, including the…

Virally labeled neurons (red) and astrocytes (green) in a cortical spheroid derived from human induced pluripotent stem cells. THUNDER Model Organism Imagerwith a 2x 0.15 NA objective at 3.4x zoomwas used to produce this 425 μm Z-stack (26 positions), which is presented here as an Extended Depth of Field(EDoF)projection.

Neuroscience Images

Neuroscience commonly uses microscopy to study the nervous system’s function and understand neurodegenerative diseases.
