  1. 11. Etablering av ett sederingsprotokoll för optisk koherenstomografi (OCT) på hund

    University essay from SLU/Dept. of Clinical Sciences

    Author : Albin Hilmersson; [2021]
    Keywords : sedering; medetomidin; ketamin; butorfanol; Zoletil; sederingsprotokoll; OCT; Optisk koherenstomografi;

    Abstract : Under 90-talet utvecklades en ny teknik för ögonundersökning, kallad optisk koherenstomografi (OCT). Tekniken kan åskådliggöra delar av ögat vilka tidigare enbart kunnat ses histologiskt. OCTtekniken har inom humanvården etablerats som en rutinmässig undersökning som utförs av oftalmologer i diagnostiskt syfte. READ MORE

  3. 12. Comparison of Lectins and their suitability in Lectin Affinity Chromatography for isolation of Glycoproteins

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Pontus Andersson; [2020]
    Keywords : biotechnology; lectins; chromatography; glycoproteins; lectin affinity chromatography; LAC; ConA; Concanavalin A; bioteknik; lektiner; kromatografi; affinitetskromatografi; glykoproteiner; ConA; Concanavalin A;

    Abstract : Virtually all extracellular proteins in humans are glycoproteins and likewise are many biopharmaceuticals. The glycosylation is directly correlated to biological function and stability of these proteins. The ability to isolate glycoproteins is thus of great importance in many applications. READ MORE

  4. 13. Biosensor based on immobilized amine transaminase for detection of amphetamine

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Clara Öh; [2020]
    Keywords : amine transaminases ATA ; enzyme immobilization; biosensor; covalent immobilization; ionic immobilization; amphetamine; histidine-tagged enzyme; Poly methyl methacrylate PMMA ;

    Abstract : Amine transaminases (ATA) catalyse the transfer of an amino group from one molecule and replaces a ketone or aldehyde with the amino group, the amino group on the amino-donor is replaced with a ketone or aldehyde. This enzyme, ATA from Chromobacterium violaceum, has previously been used to catalyse the reaction involving amphetamine, therefore, it might be possible to use this enzyme to convert amphetamine and the product absorbs in the UV spectrum and can therefore be measured spectrophotometrically.

  5. 14. Heterologous expression and purification of Nicotiana benthamiana Cellulose synthase-like B (NbCslB)

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Olivia Ståhl; [2020]
    Keywords : Biotechnology; Cellulose Synthase-Like B; Glycoscience; Glycosyltransferase; Hemicellulose; Nicotiana benthamiana; Bioteknik; Cellulosasyntasliknande B; Glykosyltransferas; Glykovetenskap; Hemicellulosa; Nicotiana benthamiana;

    Abstract : Hemicelluloses are synthesized by proteins encoded by genes from the cellulose synthasegene superfamily. One subgroup of this gene family is the cellulose synthase-like B, which islargely uncharacterized and unexplored. The common model organism Nicotianabenthamiana has one such gene in its genome, NbCslB, encoding a membrane protein. READ MORE

  6. 15. Development of a Water Activity Control and Reaction Monitoring System for Acidolysis and Transesterification Reactions using Immobilized Lipases in a Rotating Bed Reactor

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Eimantas Gladkauskas; [2019]
    Keywords : Enzyme; Enzymes; Immobilized enzyme; bioreactor; rotating bed reactor; acidolysis; transesterification; arduino; water activity; thermodynamic water activity; Enzyme activity; automatic reaction tracking; reaction tracking; biotechnology; electrical engineering; relative humidity; spinchem; enzymatic synthesis; water activity control; process automation; lipases; lipase; bioteknik; Technology and Engineering;

    Abstract : Controlled water activity in an enzymatic reaction can influence enzyme activity and productivity. A small layer of water around an enzyme gives it a required flexibility to catalyze reactions at a higher rate in contrast with the one that is dry (Adlercreutz, Dicko, Larsson, & Månsson, 2017).
