Power and limitations of electrophoretic separations in proteomics strategies [PDF]

open access: yes, 2009
Proteomics can be defined as the large-scale analysis of proteins. Due to the complexity of biological systems, it is required to concatenate various separation techniques prior to mass spectrometry.

The development of a purification procedure for Peptide:n-Glycosidase A from Prunus amygdalus : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Biochemistry at Massey University [PDF]

open access: yes, 1997
Peptide-N4-acetyl-β-glucosaminyl) asparagine amidases cleave the amide bond between N-linked glycans at N-acetylglucosamine and asparagine, liberating intact oligosaccharide chains from glycoproteins. Although PNGase A is commonly used by glycobiologists

Trapped ion mobility spectrometry and PASEF enable in-depth lipidomics from minimal sample amounts

open access: yes, 2020
A comprehensive characterization of the lipidome from limited starting material remains very challenging. Here we report a high-sensitivity lipidomics workflow based on nanoflow liquid chromatography and trapped ion mobility spectrometry (TIMS).

Large scale localization of protein phosphorylation by use of electron capture dissociation mass spectrometry. [PDF]

open access: yes, 2009
We used on-line electron capture dissociation (ECD) for the large scale identification and localization of sites of phosphorylation. Each FT-ICR ECD event was paired with a linear ion trap collision-induced dissociation (CID) event, allowing a direct ...

Determination of Cyanogenic Compounds in Edible Plants by Ion Chromatography

open access: yesToxicological Research, 2013
Cyanogenic glycosides are HCN-producing phytotoxins; HCN is a powerful and a rapidly acting poison. It is not difficult to find plants containing these compounds in the food supply and/or in medicinal herb collections.
