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…

Universal PAINT – Dynamic Super-Resolution Microscopy

Super-resolution microscopy techniques have revolutionized biology for the last ten years. With their help cellular components can now be visualized at the size of a protein. Nevertheless, imaging…

Nobel Prize 2013 in Physiology or Medicine for Discoveries of the Machinery Regulating Vesicle Traffic

On October 7th 2013, The Nobel Assembly at Karolinska Institutet has decided to award The Nobel Prize in Physiology or Medicine 2012 jointly to James E. Rothman, Randy W. Schekman and Thomas C. Südhof…

Controlling the TIRF Penetration Depth is Mandatory for Reproducible Results

The main feature of total internal reflection fluorescence (TIRF) microscopy is the employment of an evanescent wave for the excitation of fluorophores instead of using direct light. A property of the…
