How to do a Proper Cell Culture Quick Check

In order to successfully work with mammalian cell lines, they must be grown under controlled conditions and require their own specific growth medium. In addition, to guarantee consistency their growth…
Combining spectrally resolved detection and fluorescence lifetime multiplexing

Live-Cell Fluorescence Lifetime Multiplexing Using Organic Fluorophores

On-demand video: Imaging more subcellular targets by using fluorescence lifetime multiplexing combined with spectrally resolved detection.

Harnessing Microfluidics to Maintain Cell Health During Live-Cell Imaging

VIDEO ON DEMAND - In this episode of MicaCam, we will use microfluidics to explore the effect of shear stress on cell morphology, examine the effect of nutrient replenishment on cellular growth during…
Living HeLa cells stained with WGA-488 (yellow), SPY-Actin (cyan), and SiR-Tubulin (magenta). Instant Computational Clearing (ICC) was applied.

How to Perform Dynamic Multicolor Time-Lapse Imaging

Live-cell imaging sheds light on diverse cellular events. As many of these events have fast dynamics, the microscope imaging system must be fast enough to record every detail. One major advantage of…
Two-color caspase assay with tile scan. U2OS cells were treated with the nuclear marker DRAQ5 (magenta) and CellEvent™ (yellow).

Following Multiple Events during Staurosporine Apoptosis

VIDEO ON DEMAND - In this episode of MicaCam, we show how adding additional markers to an apoptosis kit can markedly increase the amount of information a researcher can obtain from the same…
Protist Paramecium (Paramecium tetraurelia) stained to show the nucleus

AI-Enabled Spatial Analysis of Complex 3D Datasets

VIDEO ON DEMAND - This edition of MicaCam offers practical advice on the extraction of publication grade insights from microscopy images. Our special guest Luciano Lucas (Leica Microsystems) will…
MDCK cysts on day 9

How To Perform Fast & Stable Multicolor Live-Cell Imaging

With the help of live-cell imaging researchers gain insights into dynamic processes of living cells up to whole organisms. This includes intracellular as well as intercellular activities. Protein or…
