Ein chirales, sattelförmiges Nanographen mit zwei Heptagon‐integrierten [4]Helicenen

Angewandte Chemie, EarlyView.
Wir präsentieren eine neuartige Synthesestrategie für ein chirales, sattelförmiges Nanographen (cSNG) über eine zweistufige Oxidation eines prochiralen Anthracen‐Vorläufers. Die Scholl‐Oxidation liefert zunächst ein Schlüsselzwischenprodukt mit sp3‐defekten Heptagonen, die anschließende oxidative Dehydrierung ergibt das vollständig konjugierte cSNG ...

Improved proteomic analysis of nuclear proteins, as exemplified by the comparison of two myelo\"id cell lines nuclear proteomes [PDF]

, 2012
One of the challenges of the proteomic analysis by 2D-gel is to visualize the low abundance proteins, particularly those localized in organelles. An additional problem with nuclear proteins lies in their strong interaction with nuclear acids.

High-throughput discrimination of bacteria isolated from Astacus astacus and A. leptodactylus

Knowledge and Management of Aquatic Ecosystems, 2014
Bacterial diseases and pathogens of crayfish are common, widespread, and occasionally causing serious mortalities. In order to take rapid measures for correct treatment of crayfish diseases, the turnover time and accuracy in bacterial

The discriminatory power of MALDI-TOF mass spectrometry to differentiate between isogenic teicoplanin-susceptible and teicoplanin-resistant strains of methicillin-resistant Staphylococcus aureus [PDF]

, 2017
To explore the discriminatory power of matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) for detecting subtle differences in isogenic isolates, we tested isogenic strains of Staphylococcus aureus differing in ...

Reactive trityl derivatives: stabilised carbocation mass-tags for life sciences applications [PDF]

, 2008
The rational design of novel triarylmethyl (trityl)-based mass tags (MT) for mass-spectrometric (MS) applications is described. We propose a "pKR+ rule" to correlate the stability of trityl carbocations with their MS performance: trityls with higher pKR+

MALDI-TOF mass spectroscopy of yeasts and filamentous fungi for research and diagnostics in the agricultural value chain

Chemical and Biological Technologies in Agriculture, 2017
Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS; MALDI biotyping) has become a standard tool for the accurate, rapid, and economical identification of pathogens in the clinical diagnostics laboratory. The method

Cellular O-Glycome Reporter/Amplification to explore O-glycans of living cells [PDF]

, 2015
Protein O-glycosylation has key roles in many biological processes, but the repertoire of O-glycans synthesized by cells is difficult to determine. Here we describe an approach termed Cellular O-Glycome Reporter/Amplification (CORA), a sensitive method ...
