1. A study of some operational parameters in expanded bed adsorption of proteins
Sammanfattning : .... LÄS MER
2. Fast isolation of proteins from bioreactors using affinity chromatography techniques
Sammanfattning : The purification of proteins from raw materials like fermentation broth and other biological sources usually involves several purification steps and is rather time consuming and expensive. This is a major concern in the production of many important protein products e.g. pharmaceuticals such as insulin and blood coagulation factors. LÄS MER
3. Production and engineering of a xyloglucan endo-transglycosylase from Populus tremula x tremuloides
Sammanfattning : The aim of this work was to develop a production process for the enzyme xyloglucan endo-transglycosylase from Populus tremula x tremuloides (PttXET16-34). The natural transglycosylating activity of this enzyme has previously been employed in a XET-Technology. LÄS MER
4. Effects of fusion tags on protein partitioning In aqueous two-phase systems and use in primary protein recovery
Sammanfattning : The two techniques aqueoustwo-phase partitioning and expanded bed adsorption that bothare suitable for primary protein recovery were studied. Most ofthe work was focused on partition in aqueous two-phase systemsand in particular on the possibility to effect the partitionbehaviour by fusion of short peptide tags or protein domains tothe target protein.

5. Polyelectrolytes and Polycomplexes in Biotechnology
Sammanfattning : Polyelectrolytes and polyelectrolyte complexes (PECs) are characterized by many useful properties that endow them with high potential in different areas of biotechnology. This thesis describes the development and analyses of some new systems and methods utilizing poly(acrylic acid) (PAA), poly(methacrylic acid) (PMA), poly (N-ethyl-4-vinylpyridinium bromide) (PEVP) and PMA-PEVP complexes.
