Biologicky aktivní peptidy. Sborník z 9. České a Slovenské peptidové konference
Slaninová, Jiřina
The Proceedings give the reader a summary of research concerning peptides caried out in Czech Republic and Slovakia.
Fyzikálně-chemická charakterizace peptidů a bílkovin kapilárními elektromigračními metodami
Kašička, Václav ; Koval, Dušan ; Šolínová, Veronika ; Sázelová, Petra ; Prusík, Zdeněk
High-performance capillary electromigration methods, zone electrophoresis, isotachophoresis, isoelectric focusing, affinity electrophoresis and electrokinetic chromatography, are presented as powerful tools for physicochemical characterization of peptides and proteins.
Separace syntetických oligopeptidů a enantiomerů terbutalinu kapilární zónovou elektroforézou s elektroosmotickým tokem řízeným radiálním elektrickým polem
Sázelová, Petra ; Kašička, Václav ; Koval, Dušan ; Prusík, Zdeněk
The home-made device for capillary zone electrophoresis (CZE) with electroosmotic flow (EOF) controlled by radial electric field has been used for separation of oligopeptides (diglycine, triglycine) and terbutaline enantiomers.
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.
Separation of structurally related peptides by open-tubular capillary electrochromatography using (metallo)porphyrins as the adsorbed stationary phase
Charvátová, Jana ; Kašička, Václav ; Barth, Tomislav ; Deyl, Zdeněk ; Mikšík, Ivan ; Král, V.
Four octapeptides, derivatives of the B23-B30-fragment of the B-chain of human insulin withminor changes in their sequences were studied as model analytes. Separations were performed both in alkaline (pH 9.0) and acidic (pH 2.25) background electrolytes.
Qualitative and quantitative microanalysis and preparative purification of biopeptides by capillary and continuous free-flow electrophoresis
Kašička, Václav ; Prusík, Zdeněk ; Sázelová, Petra ; Ježek, Jan ; Jiráček, Jiří ; Hlaváček, Jan ; Velek, Jiří ; Barth, Tomislav
High-performance capillary electrophoresis (HPCE) has been applied to qualitative and quantitative analysis of several biologically active peptides and their derivatives and fragments, e.g. insulins, insect oostatic hormones, and peptide and glycopeptide dendrimers.
Receptor-selective enkephalin analogs
Pencheva, N. ; Barth, Tomislav
We investigated the opioid profiles of [Cys2]-enkephalin (enk) analogs and [D-Ala2,Leu5]-enkephalyl-Arg (dalargin) in in vitro bioassay system. The results showed that incorporation of hydrophilic Cys(O2NH2)2 into the enk molecule greatly increases the potency and selectivity of the analogs to ë-opioid receptors, while substitution of D-Ala2 and Arg6 into the molecule of [Leu5]-enk, to ć-opioid receptors.
