Top-down analysis of immunoglobulin G isotypes 1 and 2 with electron transfer dissociation on a high-field Orbitrap mass spectrometer

Yury Tsybin, Luca Fornelli, Daniel Ayoub

The increasing importance of immunoglobulins G (IgGs) as biotherapeutics calls for improved structural characterization methods designed for these large (similar to 150 kDa) macromolecules. Analysis workflows have to be rapid, robust, and require minimal s ...

Aluminium Foil as Single-Use Substrate for MALDI-MS Fingerprinting of Different Melanoma Cell Lines

Hubert Girault, Horst Pick, Liang Qiao, Fernando Cortes Salazar, Yingdi Zhu, Alexandra Bondarenko

Herein, we present the intact cell matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for the fingerprinting of human melanoma cancer cell lines grown on aluminium foil. To perform the MALDI-MS assay, melanoma cells were cultured on a ...

Mass Barcode Signal Amplification for Multiplex Allergy Diagnosis by MALDI-MS

Hubert Girault, Natalia Gasilova, Liang Qiao, Xiaoqin Zhong

A highly sensitive method based on mass-barcoded gold nanoparticles (AuNPs) and immunomagnetic separation has been developed for multiplex allergy diagnosis by MALDI mass spectrometry in a component-resolved manner. Different analytical probes were prepare ...

The Origin of the Catalytic Activity of a Metal Hydride in CO2 Reduction

Andreas Züttel, Corsin Battaglia, Shunsuke Kato, Laetitia Bernard

Atomic hydrogen on the surface of a metal with high hydrogen solubility is of particular interest for the hydrogenation of carbon dioxide. In a mixture of hydrogen and carbon dioxide, methane was markedly formed on the metal hydride ZrCoHx in the course of ...

Selective Trapping of DNA Using Glass Microcapillaries

Nadanai Laohakunakorn

We show experimentally that an inexpensive glass microcapillary can accumulate lambda-phage DNA at its tip and deliver the DNA into the capillary using a combination of electro-osmotic flow, pressure-driven flow, and electrophoresis. We develop an efficien ...

Comparing Direct and Indirect Thrust Measurements from Passively Fed and Highly Ionic Electrospray Thrusters

Herbert Shea, Simon Dandavino, Daniel George Courtney

Highly ionic beams of several hundred microampere per squared centimeter have been measured from porous glass ionic liquid electrospray sources fabricated using a conventional mill. The thrust output from three prototype devices, two emitting the ionic liq ...
