Illumina Inc. is using the same fiber optic technology that underlies the telecommunications industry to develop genomic and drug discovery arrays that it believes are smaller and more versatile than competing technologies, while at the same time allowing for higher throughput and cost advantages. The company is initially using the technology for single nucleotide polymorphism (SNP) genotyping and plans to extend its applications to RNA and protein profiling and small molecule high throughput screening.
