The efficient approaches for enzymatic digestion of plant proteins
Dyčka, Filip ; Bobáľ, P. ; Bobálová, Janette
In this work the fast and efficient methods applying ultrasound and infrared radiation were employed for in-gel digestion of proteins extracted from Hordeum vulgare. These techniques can be used instead of time consuming conventional protocol prior mass spectrometry analysis. The comparative study indicates that the examined protocols are able to enhance digestion efficiency and protein identification.
Proteomic evaluation of MCF-7 human breast cancer cells after treatment with retinoic acid isomers: Preliminary insights
Flodrová, Dana ; Benkovská, Dagmar ; Macejová, D. ; Bialešová, L. ; Brtko, J. ; Bobálová, Janette
The effects of 9-cis retinoic acid and all-trans retinoic acid in human MCF-7 breast cancer line have been investigated. The total cell proteins were extracted and separated on 1D SDS-PAGE. The proteins were subsequently in-gel digested by trypsin and identified by MALDI-TOF/TOF.
Capillary electrophoresis with contactless conductivity detection of cationic-derivatized oligosaccharides
Partyka, Jan ; Foret, František
The oligosaccharides were derivatized by quaternary ammonium label and separated by CE with contactless conductivity detection.
MALDI-TOF MS of Dickeya and Pectobacterium species - Characterization of plant pathogenic bacteria
Šalplachta, Jiří ; Kubesová, Anna ; Horký, J. ; Horká, Marie
MALDI-TOF MS was applied to reliable characterization of Dickeya and Pectobacterium species in this study. Our results confirm suitability of suggested analytical approach for efficient bacterial differentiation of species based on species specific mass fingerprints. MALDI-TOF MS of intact bacterial cells require minimum sample handling and is less time-consuming compared to conventional methods.
Seasonal variations of metals and ions in PM1 aerosol in Brno and Šlapanice
Mikuška, Pavel ; Křůmal, Kamil ; Vojtěšek, Martin ; Kubátková, Nela ; Večeřa, Zbyněk
Contribution compares the concentrations of metals and ions in atmospheric aerosols fraction PM1 in Brno and Šlapanice and identifies emission sources of aerosols.
Sub-, near- and supercritical water in analytical separations and instrumentation development
Karásek, Pavel ; Šťavíková, Lenka ; Hohnová, Barbora ; Planeta, Josef ; Moravcová, Dana ; Horká, Marie ; Šlais, Karel ; Roth, Michal
Applications and prospects of subcritical and supercritical water in analytical separations and separation technologies are discussed and illustrated with several examples.
Bioanalytical ICP – MS Method for Quantification of Potassium Changes in the Cells and Supernatants after Action of CyaA Toxin
Petry-Podgórska, Inga ; Matoušek, Tomáš ; Wald, Tomáš ; Šebo, Peter ; Mašín, Jiří ; Dědina, Jiří
The publication presents a bioanalytical ICP-MS method applied to the quantification of changes of intra- and extracellular potassium concentration after action of the pore-forming adenylate cyclase toxin (CyaA) from the bacterium Bordetella pertussis.
Highly sensitive determination of cationic pesticides in orange juice by capillary isotachophoresis-electrospray ionization - mass spectrometry with advanced electrolyte tuning
Malá, Zdeňka ; Pantůčková, Pavla ; Gebauer, Petr ; Boček, Petr
In this contribution we present an innovative way to easy, fast and highly sensitive analyses by capillary electrophoresis with electrospray ionization mass spectrometric (ESI-MS) detection. The new method is designed to be applied to ESI-compatible electrolytes (e.g. ammonium acetate) and offers advanced tuning of selectivity conditions within a wide range of analyte mobilities.
Nano column gradient separations: Implementation of simple splitless gradient generator with integrated sample delivery
Šesták, Jozef ; Duša, Filip ; Moravcová, Dana ; Kahle, Vladislav
Automated liquid chromatographic system based on simple splitless gradient generation principle and with integrated sample delivery has been assembled and tested.
