In this chapter, we describe the use of Illumina® Infinium® HD Assay in conjunction with Illumina's EPIC Methylation 8-sample array platform to obtain glioblastoma molecular profiles. The procedure spans four days, and can be performed by a single laboratory technician. Starting with as little as 250 ng of DNA input, this method allows the flexibility to begin with DNA derived from either formalin-fixed, paraffin-embedded (FFPE) or fresh tissue and is compatible with an Illumina iScan or HiScan system.
