title: A highly sensitive resonance Rayleigh scattering method to discriminate a parallel-stranded G-quadruplex from DNA with other topologies and structures.
abstract: The RRS intensities are significantly increased only when a parallel-stranded G-quadruplex is added to Mg(2+) solution owing to the formation of G-wires between them, but the others cannot. So, we constructed a new and highly sensitive RRS method to discriminate a parallel-stranded G-quadruplex from DNA with other topologies and structures.
