  1. 1. Surface functionalization of cellulose fibers and exploration of its influence in ion exchange chromatography

    University essay from KTH/Fiber- och polymerteknologi

    Author : Anna Wessén; [2023]
    Keywords : Ion-exchange chromatography; membrane chromatography; surface extension; grafting; copolymerization; free-radical polymerization; Jonbyteskromatografi; membrankromatografi; ytförlängning; ympning; sampolymerisation; fri radikal polymerisation;

    Abstract : Kromatografiska metoder kan användas för en mängd olika tillämpningar, inklusive separation, rening och analys av biomolekyler och kemikalier. Membrankromatografi är en av de nya kromatografiteknikerna som expanderar snabbt eftersom den tillåter hög masstransport genom den stationära fasen, vilket resulterar i en mer tidseffektiv process.

  3. 2. Towards time-resolved cryo-EM of SARS-CoV-2 replication-transcription complex and Staphylococcus aureus DNA gyrase

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Anna Králová; [2023]
    Keywords : time-resolved cryo-EM; DNA gyrase; SARS-CoV-2; replication-transcription complex; protein purification;

    Abstract : Time-resolved cryo-EM has already provided ground-breaking discoveries in various fields, including structural biology, biochemistry, and drug development. Compared to traditional structural biology methods where mostly stabilized conformations are reconstructed, the main advantage of time-resolved cryo-EM is its ability to capture dynamic processes in biological samples at near-atomic resolution, which allows for studying biological structures as they change and interact in real-time.

  4. 3. Orbit-simulator for downstream processes

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Andreas Malmström; [2022]
    Keywords : Chemical engineering; Process simulation; Downstream processes; Orbit; Preparative chromatography; Python; Lumped Rate Models; Technology and Engineering;

    Abstract : In an ever more digitilized society, the transition is palpable also in the pharmaceutical industry. The control system Orbit was developed at the department of chemical engineering at Lund University, to be able to automate downstream processes based on the ÄKTA-system. READ MORE

  5. 4. Development of MALS methods for exosome size analysis

    University essay from KTH/Kemi

    Author : Terese Andersson; [2022]
    Keywords : Exosomes; Multiangle light scattering; MALS; extracellular vesicles; Exosomer; Multiangle light scattering; MALS; extracellulara vesiklar;

    Abstract : Exosomer är extracellulära vesiklar i nanostorlek som frigörs från cellerna till den extracellulära matrisen. Exosomer är laddade med nukleinsyror, proteiner, och lipider, och fungerar som kommunikatorer mellan celler. Det har gjort dem mycket attraktiva for forskning inom terapi, diagnostik och transport av läkemedel. READ MORE

  6. 5. Preparative chromatographyfor modified oligonucleotides : Method development for modified oligonucleotides, fromanalytical to preparative chromatography

    University essay from Karlstads universitet

    Author : Rebecka Jasinski; [2021]
    Keywords : oligonucleotides; preparative chromatography; scaling-up; ion-pair chromatography; dibutylamine; oligonukleotider; preparativ kromatografi; uppskalning; jonparskromatografi; dibutylamin;

    Abstract : Synthetic oligonucleotides, which are short strings of DNA or RNA, are a grooving area of importance for the pharmaceutical industry and for companies that manufacture diagnostic components. The manufacturing process of synthetic oligonucleotides involves many complex processes that use separation and purification techniques like ion-exchange chromatography, ion-pair reversed phase chromatography and ultra-performance liquid chromatography.
