  1. 11. Detecting Chromatography Unit Degradation : Comparison of single- and multi-point techniques implemented in system control and monitoring software

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Max Markensten; [2023]
    Nyckelord :PCA; SOP-MPT; Fibro; chromatography; affinity A;

    Sammanfattning : Chromatography units, used in the production of pharmaceuticals, degrade with use and need to be changed or repackaged. This study investigates the effectiveness of two statistical methods, principal component analysis and simple and one-point multiparameter technique, for determining degradation in the Fibro chromatography unit.

  3. 12. Ion pair chromatography of carboxylic and sulfonic acids with trialkylamines : An investigation of the relationship between the adsorption isotherm of the IPR and the retention factor of the analyte

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Karl Kullberg; [2023]
    Nyckelord :;

    Sammanfattning : Ion pair chromatography has found many uses within analytical chemistry and understanding of the chromatographic process with an ion-pairing reagent have been studied since the 1970s. The adsorption of the Ion-pairing reagent to the stationary phase is understood to be important and many studies have been dedicated to looking at the adsorption isotherms of the earlier quaternary alkylammonium ions.

  4. 13. Characterization of Mitilysin Pores by Cryo-electron Microscopy

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Vladimir Novakovic; [2023]
    Nyckelord :Mitilysin; Mly; Structural Biology; Cryo-EM; pore; toxin; pore forming proteins; pore forming toxins; PFP; PFT;

    Sammanfattning : Pore forming toxins (PFTs) are a large group of proteins found mainly in bacteria with some exceptions found in animals. They bind and form pores in their target membranes and form pores, which leads to cell death. Among these are cholesterol-dependent cytolysins (CDC), which require the presence of cholesterol to bind target membranes. LÄS MER

  5. 14. Exploratory study of ion pair liquid chromatography separation methods and sample preparation procedures – for quantification of amount 5’capped and uncapped mRNA

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Felicia Lindström; [2023]
    Nyckelord :;

    Sammanfattning : Using ion pair chromatography, separation and analysis of shorter mRNA fragments was possible. The aim of the study was to develop a separation method for quantitation of 5’capped versus uncapped mRNA. Cleavage of mRNA was performed by complementary probes and the enzyme RNase H which created shorter mRNA fragments containing the 5’ end. LÄS MER

  7. 15. Identification of Vanadium-Binding Ligands in White Wine

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Freja T Trybom; [2023]
    Nyckelord :Vanadium; LD converter slag; wine; food waste; recycling.;

    Sammanfattning : Vanadin är en värdefull metall och kan lakas ur LD (Linz-Donawitz)-slagg med hjälp av vin. Ligander i vinet som lakar vanadin från LD-slagg studerades i denna rapport med mål att identifiera några av deras egenskaper såsom apparent molekylmassa och spektral information. LÄS MER
