Illumina, Inc. has introduced the Infinium HumanLinkage-12 Genotyping BeadChip, the company's fifth multi-sample Infinium BeadChip and first standard panel to take advantage of a twelve-sample format for linkage analysis. This new addition to the Linkage portfolio complements the GoldenGate Human Linkage V Panel, which is particularly suitable for degraded samples such as formalin-fixed, paraffin-embedded (FFPE). The HumanLinkage-12 chip is also available for researchers interested in conducting linkage analysis studies via Illumina's FastTrack Genotyping Service. Linkage analysis maps the location of disease-causing loci by identifying genetic markers that are co-inherited with the phenotype of interest.
