ProteomicsProteome analysis by simple and stable nanoESI spray system
We developed InSpIon system capable of stable nanoESI spray. Here, K562 cell digests were measured by DDA-MS and DIA-MS with the typical open nanoESI spray system (Open system) and the spray system inserted spray tip head into ion transfer tube (Insertion-ITT system), and the InSpIon system.

ProteomicsTapered-tip Capillary Electrophoresis Nano-electrospray Ionization Mass Spectrometry for Ultrasensitive Proteomics: The Mouse Cortex
We have enabled ultrasensitive proteomics of limited protein digests by developing a tapered-tip nanoelectrospray ionization (nanoESI) interface for microanalytical capillary electrophoresis (CE) high resolution mass spectrometry (HRMS). CE-nanoESI-HRMS allowed us to detect 260 zmol angiotensin II (...

ProteomicsElectrospray ionization in concentrated acetonitrile vapor improves the performance of mass spectrometry for proteomic analyses
Suppressing the background interferences and enhancing the analyte signals are long-term goals in high performance electrospray ionization mass spectrometry (ESI-MS) analyses. We observed that performing electrospray in the presence of a concentrated acetonitrile atmosphere suppresses background int...

ProteomicsPurified QPCTL was incubated with the SHP2 (aa 17-35) and SHP2 (aa 57-75) peptide, and the modification of SHP2 (aa 17-35) was analyzed by nano-electrospray ionization mass spectrometry (nanoESI-MS)
Purified QPCTL was incubated with the SHP2 (aa 17-35) peptide, and the modification of SHP2 (aa 17-35) was analyzed by nano-electrospray ionization mass spectrometry (nanoESI-MS). The modification of SHP2 (aa 17-35) alone (without co-incubation with purified QPCTL protein) was monitored by nanoelect...

ProteomicsMass spectrometry-guided molecular modeling predicts the interaction interface for a camelid single-domain antibody targeting the Plasmodium falciparum circumsporozoite protein’s C-terminal domain
To improve malaria diagnostics novel detector systems with high specificity and sensitivity are required. The malarial antigen PfCSP-Cext was selected to generate the camelid single domain antibody sdAbCSP1, which is intended to be used as capture device for detecting PfCSP-Cext in serum of acutely ...
