Loodus- ja täppisteaduste valdkondFörster resonance energy transfer (FRET) is a routinely apply photoluminescence technology in high throughput screening in drug discovery. It involves the transfer of energy between two luminescence molecules, the donor and the acceptor in close proximity. In this thesis, we describe the application of the approach exploiting time-resolved measurement of intensity of FRET (TR-FRET) from terbium donor luminophore to fluorescent dye Alexa Fluor 647, for the measurement of the concentration of a specific protein kinase Pim2 in a solution-phase homogenous assay. This method is based on the simultaneous binding of a specific PK to both a luminophore ARC-type probe inhibitor and a fluorescently labelled monoclonal antibody specific to the PK. In case specific IgG labelled with Alexa Fluor 647 acting as acceptor fluorophore is combined in solution with donor luminophore (lanthanide chelate labelled) ARC-probe and the protein kinase of interest, the formation of a triple complex antibody:protein kinase:ARC-probe can be measured by time-resolved measurement of FRET intensity. First, we were able to determine the active concentration of the PK, using a flurescently labelled ARC-type inhibitor of the PK’s active site. Second, we were able to prove the detection of a specific PK by formation of high a FRET signal between a luminophore ARC-type probe PK inhibitor as donor and a fluorescently labelled antibody specific to the PK as acceptor. In addition, formation of the triple complex between ARC-type inhibitor:PK:mAb(Pim2) was confirmed by addition of another ARC-type inhibitor in the well were maximal FRET signal ratio was observed. The determined limit of quantification of the assay was 8 nM, that points to high sensitivity of this homogeneous analytical method. The approach described in this thesis, could be used as a rapid medical diagnostic tool for PK detection and analysis.Kirje Role of the stringent response in antibiotic tolerance of Escherichia coli(Tartu Ülikool, 2016) Alves Oliveira, Sofia Raquel; Hauryliuk, Vasili; Varik, Vallo; Tartu Ülikool. Loodus- ja täppisteaduste valdkondThe stringent response is a near-universal bacterial adaptation system control mediated by accumulation of two guanine nucleotides ppGpp and pppGpp, collectively known as (p)ppGpp. The response monitors several environmental stress inputs, such as nutrient limitation and heat shock and remodels bacterial physiology in order to overcome the challenges. In Echerichia coli (p)ppGpp levels controlled by two enzymes – RelA and SpoT, the namesakes of RelA SpoT Homologue (RSH) protein family. The stringent response is associated to induction of virulence, antibiotic resistance and was recently suggested to be the driving force behind the formation of so-called persister cells – antibiotictolerant phenotypic variants in antibiotic-sensitive population. Since drug resistance and tolerance constitute a significant public health threat, understanding the connection amongst (p)ppGpp, antibiotic treatment and persistence is of great importance.Kirje Validation of alpha spectrometric analytical measurement procedure for the determination of Polonium-210 (210Po) in environmental samples(Tartu Ülikool, 2016) Gyakwaa, Francis; Tkaczyk, Alan, juhendaja; Kiisk, Madis, juhendaja; Ozden, Banu, juhendaja; Vaasma, Taavi, juhendaja; Tartu Ülikool. Loodus- ja täppisteaduste valdkondThe thesis aims at finding suitable alpha spectrometry measurement procedure and validating it to be implemented in the laboratory where it can be used for routine analytical procedure for the determination of 210Po in environmental samples. In establishing if the procedure is fit for the intended purpose, the following validation parameters were determined: trueness, accuracy (En-value, z-score), relative bias, and tracer recovery. Also the main sources of uncertainty and their percentage contributions were established.
