To monitor crystallization processes a special camera setup to measure the crystal size and 3D shape distribution was developed.
The setup consists of two high-speed cameras that are positioned orthogonally to one another such that a precise overlap of both fields of view can be achieved. The setup further contains a specially designed flow-through cell that allows to observe the crystal suspension from both camera directions and given the opportunity to temperate the solution within the cell. ...

Engineering light distributions in a three-dimensional volume to achieve selective illumination profiles is an instrumental task shared by many optical and microscopy techniques. The optimization of the light distribution can lead to significant enhancement of relevant performance figures and ultimately to the extension of the instrument or experimental protocol capabilities^1,2,3,4,5. Targeted illumination profiles can be used either to mechanically interact with molecules at nanometer ...

Simultaneous sensing of oxygen content and temperature within a living object is crucial to monitor its biochemical reactions and to evaluate its health condition. Non-invasive sensors used for this purpose feature optical read-out. These sensors detect changes in phosphorescence (decay time or emission intensity) of a phosphorescent compound and the delayed fluorescence intensity of a fluorescent compound induced by an increase of temperature and/or oxygen. Unfortunately, the temperature and ...

We present an extremely sensitive, reliable and fast novel Lysine deacetylase (KDAC) assay, which can be performed in a continuous format. This novel KDAC assay is based on Firefly luciferase harboring an acetylation on an essential active site lysine, incorporated by genetic code expansion.

We furthermore offer a bacterial selection system that can help engineer KDACs. The selection system uses a reporter enzyme inactivated by lysine modifications at an essential active site residue, thereby ...

Carbohydrates form one of the major classes of biological macromolecules in living organisms, but structural analysis and the quality control of carbohydrate structures represent a major challenge due to the frequent occurrence of isomers that are difficult to distinguish using established techniques.

Changes in protein glycosylation are frequently identified in the context of diseases. For example, alterations in N-glycan profiles from blood plasma have been found to correlate with pathological ...

A simple, one-step assay for reliable measurements of NAD(H) and NADP(H) in complex samples, with various applications such as enzymatic assays, clinicals tests, and as point of care tests in the field of ageing.
