Abstract
Methods and apparatus for detecting polynucleotide hybridization in luminescence-based assays. The methods may include (1) allele-specific hybridization, using luminescence detection, (2) allele-specific oligonucleotide ligation, using dye-labeled oligonucleotide ligation with luminescence resonance energy transfer (FRET) detection, and (3) allele-specific nucleotide incorporation, using primer extension with luminescence polarization (FP) detection. More specifically, the methods may include (1) locating a sample containing a nucleic acid material at an examination site, (2) illuminating the sample, (3) detecting light transmitted from the sample, and (4) determining the presence, absence, and/or identity of a nucleic acid target in the sample using the light transmitted from the sample.
