DxS has launched a single-tube genotyping assay in its Scorpions fluorescent-detection technology line for the drug-metabolism gene UGT 1A1*28, the company said last week. The test can deliver results "within 30 minutes" and can be used with both real-time or end-point analysis, the company said.


ParAllele BioScience now offers 20,000 non-synonymous SNPs — up from 10,000 — as part of its human genotyping service, the company said last week. The latest SNP selection was obtained by genotyping "approximately 300" individuals from three ethnic populations, resulting in "more than 8 million" genotypes, the company said.


The Translational Genomics Research Institute has launched its MammaPrint gene-expression profile microarray diagnostic for breast cancer in the United States, the company said in a statement this week. The test "distinguishes between lymph node-negative breast cancer patients who would benefit from additional therapy from those who would not," the company said.
