Infection of the novel coronavirus SARS-CoV-2 can be blocked by a human monoclonal antibody
Vaccines and targeted therapeutics for treatment of the respiratory disease COVID-19, caused by the coronavirus SARS-CoV-2, are currently lacking. Based on the results of this study, it was reported…Read article
The Guide to STED Sample Preparation
This guide is intended to help users optimize sample preparation for stimulated emission depletion (STED) nanoscopy, specifically when using the TCS SP8 STED 3X nanoscope from Leica Microsystems. It…Read article
Abstracts of the 7th European Super-Resolution User-Club Meeting
The 7th Super-Resolution User Club Meeting was held in collaboration with Prof Pavel Hozák , at the Institute of Molecular Genetics of the ASCR in Prague. Keeping the event close to science is one of…Read article
The Fundamentals and History of Fluorescence and Quantum Dots
At some point in your research and science career, you will no doubt come across fluorescence microscopy. This ubiquitous technique has transformed the way in which microscopists can image, tag and…Read article
Milestones in Incident Light Fluorescence Microscopy
Since the middle of the last century, fluorescence microscopy developed into a bio scientific tool with one of the biggest impacts on our understanding of life. Watching cells and proteins with the…Read article
Testing the Münch Hypothesis of Long Distance Phloem Transport in Plants
Long distance transport in plants occurs in sieve tubes of the phloem. The pressure flow hypothesis introduced by Ernst Münch in 1930 describes a mechanism of osmotically generated pressure…Read article
Chronic Inflammation Under the Microscope
In the course of chronic inflammation certain body areas are recurrently inflamed. This goes along with many human diseases. With the help of widefield light microscopy, the underlying processes can…Read article
Multispectral Phloem-Mobile Probes: Properties and Applications
Using Arabidopsis (Arabidopsis thaliana) seedlings, we identified a range of small fluorescent probes that entered the translocation stream and were unloaded at the root tip. These probes had…Read article
