NEW YORK (GenomeWeb) – Illumina and collaborators from several consortia have developed a new genotyping microarray optimized for genome-wide association studies in populations of diverse ancestries and backgrounds.

Dubbed the Infinium Multi-Ethnic Genotyping Array, or MEGA, the San Diego vendor is offering the 1.7-million marker chip through the end of the month with an introductory price of $74 per sample, said Peter Fromen, senior director of product marketing for the company's life sciences business.
