Required products

Choose a kit size that matches the number of samples you wish to run at a time. Each kit is processed as a single batch and is not designed to be divided across multiple experiments. If you are processing several low-throughput batches, order multiple small kits.

You can choose to customize your content using  DesignStudio Microarray Assay Designer or select from a list of add-on content available as  consortia boosters. Booster add-on content is available for:

  • Multi-disease (~50,000 SNPs)

  • Common psychiatric disorders (~30,000 SNPs)

  • Direct-to-consumer wellness and lifestyle (~28,000 SNPs)

  • Oncology (~90,000 SNPs)
