Fully automated chip-based nanoelectrospray combined with electron transfer dissociation for high throughput top-down proteomics

Autor: Florina Capitan, Marilena Manea, Catalin Schiopu, Cristina Mosoarca, Alina D. Zamfir, Corina Flangea, Eugen Sisu

Publikováno v: Open Chemistry, Vol 11, Iss 1, Pp 25-34 (2013)

The conventional protocol for protein identification by electrospray ionization mass spectrometry (MS) is based on enzymatic digestion which renders peptides to be analyzed by liquid chromatography-MS and collision-induced dissociation (CID) multista

Discrimination of GalNAc (4S/6S) sulfation sites in chondroitin sulfate disaccharides by chip-based nanoelectrospray multistage mass spectrometry

Autor: Sorin Tudor, Alina Serb, Daniela G. Seidler, Eugen Sisu, Catalin Schiopu, Corina Flangea, Alina D. Zamfir

Publikováno v: Open Chemistry, Vol 7, Iss 4, Pp 752-759 (2009)

Sulfation pattern within chondroitin sulfate (CS) glycosaminoglycan (GAG) chains is an important post-translational modification that regulates their interaction with proteins. In this context, development of highly efficient and reproducible analyti
