Evaluation of negative stains for single particle analysis in electron microscopy
ĎURINOVÁ, Eva
Four negative stains, hafnium chloride and europium, samarium and gadolinium nitrates, were tested in single particle electron microscopy as potential alternatives to uranyl acetate, which is recently being widely restricted for its toxicity. The new stains were applied to a structurally well-described plant photosystem I, visualized by a transmission electron microscope and classified in a single particle analysis. The quality of the stains was evaluated by the obtained resolution and ability to provide reliable structural information.
The impact of DNA methylation on the stability and dynamics of i-motif in the ILPR promoter region
ĎURINOVÁ, Eva
The stability of i-motif structure in the promoter of the insulin gene was investigated by circular dichroism and single-molecule fluorescence resonance energy transfer. The main factor studied was the cytosine methylation and its location in the DNA sequence. Also the molecular crowding effect was examined. In addition, i-motif folding kinetics were investigated by the single molecule method.
