Fluorescence detection of single-nucleotide polymorphisms with a single, self-complementary, triple-stem DNA probe.

ABSTRACT: Singled out for its singularity: In a single-step, single-component, fluorescence-based method for the detection of single-nucleotide polymorphisms at room temperature, the sensor is comprised of a single, self-complementary DNA strand that forms a triple-stem structure. The large conformational change that occurs upon binding to perfectly matched (PM) targets results in a significant increase in fluorescence (see picture; F = fluorophore, Q = quencher).
