G-Quadruplexes As Molecular Targets For Transcriptional Control
… number of competing isoforms, were examined by electronic circular dichroism. Electromobility shift assays differentiated inter- and intra-molecular structures, further distinguishing the distribution of isoforms. Other studies included chemical footprinting, FRET compound screening, luciferase, …
