Self-Assembly of a Giant Molecular Solomon Link from 30 Subcomponents

Rosario Scopelliti, Kay Severin, Yury Tsybin, Konstantin Nagornov, Konstantin Zhurov, Clément Schouwey

The synthesis of topologically complex structures, such as links and knots, is one of the current challenges in supramolecular chemistry. The so-called Solomon link consists of two doubly interlocked rings. Despite being a rather simple link from a topolog ...

Empirical multi-dimensional space for scoring peptide spectrum matches in shotgun proteomics

Yury Tsybin, Unige Anna Laskay

Data-dependent tandem mass spectrometry (MS/MS) is one of the main techniques for protein identification in shotgun proteomics. In a typical LC MS/MS workflow, peptide product ion mass spectra (MS/MS spectra) are compared with those derived theoretically f ...

Middle-down analysis of monoclonal antibodies with electron transfer dissociation Orbitrap FTMS

Yury Tsybin, Luca Fornelli, Daniel Ayoub

The rapid growth of approved biotherapeutics, e.g., monoclonal antibodies or immunoglobulins G (IgGs), demands improved techniques for their quality control. Traditionally, proteolysis-based bottom-up mass spectrometry (MS) has been employed. However, the ...

Practical Considerations for Improving the Productivity of Mass Spectrometry-based Proteomics

Yury Tsybin, Anton Kozhinov, Luca Fornelli, Kristina Srzentic, Unige Anna Laskay, Oxana Upir

Mass spectrometry (MS) is currently the most sensitive and selective analytical technique for routine peptide and protein structure analysis. Top-down proteomics is based on tandem mass spectrometry (MS/MS) of intact proteins, where multiply charged precur ...

Iterative Method for Mass Spectra Recalibration via Empirical Estimation of the Mass Calibration Function for Fourier Transform Mass Spectrometry-Based Petroleomics

Yury Tsybin, Anton Kozhinov, Konstantin Zhurov

We describe a mass spectra recalibration method, which enables analysis of petroleum samples with Orbitrap FTMS. In this method, the mass calibration function is estimated on the basis of mass-to-charge ratios and abundances of internal calibrants without ...
