Erweiterung der Peptidligation auf Saure pH‐Bereiche und Schnittstellen mit Glykosylierten und Phosphorylierten Aminosäuren

Angewandte Chemie, EarlyView.
Ein pyridinhaltiges Ligationsauxiliar beseitigt einen wesentlichen Engpass der Peptidligationschemie. Der für die Ligation nutzbare pH‐Bereich von 2,0–7,5 hilft, Epimerisierung zu vermeiden. Die native chemische Ligation (NCL) verläuft an praktisch jeder Ligationsstelle, einschließlich Reaktionen an β‐verzweigten sowie O‑glykosylierten oder O ...

Extending Peptide Ligation to Acidic pH and Junctions Comprising Glycosylated and Phosphorylated Amino Acids

Angewandte Chemie International Edition, EarlyView.
A pyridine‐containing ligation auxiliary eliminates a major bottleneck of peptide ligation chemistry. The extended range of applicable pH values (2.0–7.5) in the ligation reaction helps to avoid epimerization. Native chemical ligation (NCL) proceeds at virtually any junction, including reactions at β‐branched amino acids, as well as O‐glycosylated or O‐

Quantification of Si in Silicone Oils by ICP-OES

Silicon, 2014
A new simple and low cost method of quantification of trace amounts of silicon (Si) in silicone oils has been developed by combining the silicone emulsion and inductively coupled plasma optical emission spectroscopy (ICP-OES) analysis. Silicone oils that contained phenyl groups in the viscosity range from 20 to 1000 mPa.s formed stable oil in water ...

Comparisons between LIBS and ICP/OES

Analytical and Bioanalytical Chemistry, 2006
In the framework of the development of new techniques, the ability of laser-induced breakdown spectroscopy (LIBS) to analyse remotely complex aqueous solutions was investigated. The jet configuration with a collimated gas stream was chosen because it appeared to be the most promising method for the LIBS probe, particularly in terms of sensitivity and ...
