Towards Unbiased Fluorophore Counting in Superresolution Fluorescence Microscopy

Authors Laitenberger O, Aspelmeier T, Staudt T, Geisler C, Munk A, Egner A Journal Nanomaterials Citation Nanomaterials 2023, 13(3), 459. Abstract With the advent of fluorescence superresolution microscopy, nano-sized structures can be imaged with a previously unprecedented accuracy. Therefore, it is rapidly gaining importance as an analytical tool in the

Artistic representation showing how an image is created using the newly developed method. Two colours – green and magenta – are emitted by fluorescing atoms in the sample (left) due to X-Ray excitation. The grey round object represents an optic casting a shadow on the detector. The algorithm then produces an actual image with two colours – the intensity of which represents the density of the fluorescing atoms within the sample. Photo: Markus Osterhoff

Colour images from the shadow of a sample

A research team at the University of Göttingen has developed a new method to produce X-ray images in colour. In the past, the only way to determine the chemical composition of a sample and the position of its components using X-ray fluorescence analysis was to focus the X-rays and scan

Translation Factor Accelerating Peptide Bond Formation on the Ribosome: EF-P and eIF5A as Entropic Catalysts and a Potential Drug Targets

Authors Mudryi V, Peske F, Rodnina M Journal BBA Advances Citation BBA Advances (2023). Abstract Elongation factor P (EF-P) and its eukaryotic homolog eIF5A are auxiliary translation factors that facilitate peptide bond formation when several sequential proline (Pro) residues are incorporated into the nascent chain. EF-P and eIF5A bind to
