摘要： Methods and apparatus for detecting single nucleotide polymorphisms in genes of interest are disclosed. A plurality of probes is immobilized on a planar waveguide. The probes comprise sequences complementary to a wildtype sequence of the gene of interest and complementary to a sequence of a known SNP in the gene of interest. A fluorescently-labeled analyte is flowed over the planar waveguide. The binding between the labeled analyte and each of the probes causes a change in the fluorescence signal. The SNP is detected by comparing the hybridization kinetics of the analyte with each of the probes. A method of detecting single nucleotide polymorphisms in a gene of interest by sequencing by hybridization is also disclosed.

摘要： Genetic polymorphisms can change protein structure and function, altering dispositions to diseases and conditions. A single nucleotide polymorphism is the smallest genetic mutation and the most difficult to detect. However, single nucleotide polymorphisms also make up 90% of known genetic mutations, thus identifying such polymorphisms is essential. Single base extension uses the affinity of one base for its complementary base to detect polymorphisms, including single nucleotide polymorphisms. Planar waveguides are used as the platform for single base extension enabling rapid, real time detection of genetic polymorphisms. Detection limits in the picomolar range can be obtained. Signals from the non-matched DNA bases are in the range of the blank signal. Detection times of 5 minutes are reported.
