Studium vztahu mezi strukturou a pohyblivostí a určování sekundární struktury biopeptidů kapilární zónovou elektroforézou
Šolínová, Veronika ; Kašička, Václav ; Koval, Dušan ; Hlaváček, Jan ; Barth, Tomislav
Capillary zone electrophoresis (CZE) has been applied to the analysis, separation and physico-chemical characterization of insect oostatic peptides, enkephalins and dalargin, and their derivatives and fragments.
Kapilární elektroforéza v silně kyselých základních elektrolytech a její užití pro separaci a charakterizaci peptidových a pseudopeptidových stereoizomerů
Kašička, Václav ; Koval, Dušan ; Šolínová, Veronika ; Sázelová, Petra ; Hlaváček, Jan ; Jiráček, Jiří
Capillary zone electrophoresis in the strongly acidic background electrolytes (pH range 1.1-3.2), has been applied for separation and physicochemical characterization of insect oostatic peptides and phosphinic pseudopeptides.
Aktuální pokroky v kapilární elektroforéze peptidů a bílkovin
Kašička, Václav ; Koval, Dušan ; Šolínová, Veronika ; Sázelová, Petra
Recent developments in particular modes of high performance capillary electromigration methods will be presented with respect to their application to analysis, preparation and physicochemical characterization of peptides and proteins.

Analysis of peptides by capillary zone electrophoresis and micellar electrokinetic chromatography
Šolínová, Veronika ; Kašička, Václav ; Koval, Dušan ; Hlaváček, Jan ; Barth, Tomislav ; Ciencialová, Alice ; Klasová, Lenka ; Straková, Jana
Two methods were used for analysis of purity of different kinds of peptides those having ionogenic groups and those devoid of ionogenic groups.
Analysis of ionic components including polypeptide and protein allergens in water extracts from the airborne dust samples by capillary isotachophoresis
Sázelová, Petra ; Kašička, Václav ; Koval, Dušan ; Peltre, G.
Water extracts of the dust samples collected in different periods in air-filtration devices in Prague car-traffic tunnels and in Parisian metro station were analyzed both in cationic and anionic capillary isotachophoresis modes.
Separation of phosphinic pseudopeptide diastereomers by CZE and RP-HPLC
Koval, Dušan ; Kašička, Václav ; Jiráček, Jiří ; Collinsová, Michaela
Capillary zone electrophoresis (CZE) and reverse phase high-performance liquid chromatography (RP-HPLC) were used for separation of diastereomers of phosphinic pseudopeptides. The migration order in CZE with their elution order in RP-HPLC was compared.
Analysis and characterization of phosphinic pseudopeptides by capillary zone electrophoresis
Koval, Dušan ; Jiráček, Jiří ; Collinsová, Michaela ; Kašička, Václav
Phosphinic pseudopeptides of general structure N-Ac-Val-Ala.psi.(PO.sub.2./sub.-CH.sub.2./sub.)Leu-Xaa-NH.sub.2./sub., where Xaa represents one of 20 proteinogenic amino acid residues were studied. Separation of diastereomers of some peptides was achieved in acid electrolyte.
