Structure approaches to study of DNA aptamers in solution

The high potential of aptamers – specifi c molecular agents based on short single-stranded nucleic acids – makes high demands on the molecules under development for the effi ciency of interaction with target biomolecules. In this work, approaches are considered for studying the spatial structure of DNA aptamers in solution using various complementary methods, which make it possible to obtain a more complete picture of the formation of the structure and conformational changes, to track the interaction with the target protein, the tendency to oligomerization, and to characterize the spatial structure of both individual molecules and complexes.
