Ultra visokotlačna kromatografija makromolekul
Maja Caf, Aleš Podgornik
Diplomsko delo
Oznake: ultra visokotlačna tekočinska kromatografija;UHPLC;kapilarne kolone;hibridni delci;delci na osnovi silike;diplomska dela;
Ultra visokotlačno tekočinsko kromatografijo so v laboratorijih razvili v poznih 90 letih prejšnjega stoletja, s ciljem doseganja hitrih analiz visoke ločljivosti pretežno na kapilarnih kolonah napolnjenih z 1–1.7 mikronskimi delci. UHPLC se pogosto uporablja v analizni kemiji za ločevanje, identifi ...

Ultra visokotlačna ionsko izmenjevalna kromatografija proteinov
Maja Caf, Aleš Podgornik, Igor Plazl, Matevž Pompe
Magistrsko delo
Oznake: ultra visokotlačna kromatografija;UHPLC;proteini;beta-laktoglobulin;zamik termodinamskega ravnotežja;magistrska dela;
Ultra visokotlačna kromatografija zagotavlja hitrejše ločevanje in manjšo porabo topil v primerjavi z običajnimi HPLC sistemi in hkrati izboljša učinkovitost kolone. To je mogoče doseči z zmanjšanjem velikosti delcev stacionarne faze in povečanjem linearne hitrosti mobilne faze [1]. Delovanje UHPLC ...

Complex protein retention shifts with a pressure increase
Anja Kristl, Maja Caf, Matevž Pompe, Aleš Podgornik
Izvirni znanstveni članek
Oznake: ionska izmenjava;zadrževanje proteinov;visok tlak;sprememba parcialnega molskega volumna;UHPLC;ion exchange;protein retention;high pressure;partial molar volume change;
Studies of protein adsorption on reversed-phase and ion exchange stationary phases demonstrated an increase in retention with increasing pressure, which is interpreted as a standard partial molar volume decrease during the transition of the protein from a mobile to a stationary phase. Investigation ...

Llimited efficacy of nanoparticle-assisted electroporation for membrane permeabilization and gene electrotransfer
Tamara Polajžer, Matej Kranjc, Slavko Kralj, Maja Caf, Rok Romih, Samo Hudoklin, Federica Rocca, Damijan Miklavčič
Izvirni znanstveni članek
Oznake: nanodelci;numerični model;elektro tansfer;
Nanoparticles (NPs) were previously explored as enhancers in electroporation due to their potential to locally amplify electric fields near cell mem branes, with gold nanoparticles (AuNPs) in particular showing promise in improving membrane permeability and gene electrotransfer (GET). In this study, ...

Modulation of contactless high intensity pulsed electromagnetic field induced electroporation and gene delivery efficacy using various nanoparticles
Tamara Polajžer, Matej Krajnc, Slavko Kralj, Maja Caf, Rok Romih, Samo Hudoklin, Vitalij Novickij, Damijan Miklavčič
Izvirni znanstveni članek
Oznake: dostavni sistemi za gene;gene delivery;
Introduction: High-intensity pulsed electromagnetic fields (HI-PEMF) can be used to trigger contactless permeabilization of the plasma membrane similar to electroporation (EP). The permeabilization efficiency and gene delivery by HI-PEMF in vitro are currently inferior to EP. It was suggested that t ...
