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…

Handbook of Optical Filters for Fluorescence Microscopy

Fluorescence microscopy and other light-based applications require optical filters that have demanding spectral and physical characteristics. Often, these characteristics are application-specific and…

Widefield Calcium Imaging with Calcium Indicator Fura2

In eukaryotic cells Ca2+ is one of the most widespread second messengers used in signal transduction pathways. Intracellular levels of Ca2+ are usually kept low, as Ca2+ often forms insoluble…

Nobel Prize 2012 in Physiology or Medicine for Stem Cell Research

The Nobel Prize recognizes two scientists who discovered that mature, specialised cells can be reprogrammed to become immature cells capable of developing into all tissues of the body. Their findings…

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…
