The Infinium HumanMethylation450 BeadChip Kit is being discontinued. We will accept orders until November 30th, 2016, or until inventory is depleted, whichever comes first. The Infinium MethylationEPIC Kit is the recommended replacement product. Illumina remains committed to providing you with high-quality support and service during this transition.

Product Highlights

The Infinium HumanMethylation450 BeadChip array offers a unique combination of comprehensive, expert-selected coverage, high sample throughput, and an affordable price, making it an ideal solution for epigenome-wide association studies (EWAS).

Powered by the revolutionary Illumina Infinium Methylation Assay, this BeadChip allows researchers to interrogate more than 485,000 methylation sites per sample at single-nucleotide resolution. Content was selected with the guidance of a consortium of methylation experts comprising 22 members that represent 19 institutions worldwide.  

The array covers 99% of RefSeq genes, with an average of 17 CpG sites per gene region distributed across the promoter, 5'UTR, first exon, gene body, and 3'UTR. It covers 96% of CpG islands, with additional coverage in island shores and the regions flanking them. Further content categories requested by the Consortium include:

  • CpG sites outside of CpG islands
  • Non-CpG methylated sites identified in human stem cells
  • Differentially methylated sites identified in tumor versus normal (multiple forms of cancer) and across several tissue types
  • CpG islands outside of coding regions
  • miRNA promoter regions

This BeadChip has a 12-sample per array format compatible with automation. This enables up to 96 samples to be run in parallel (with full LIMS support available), and requires only 500 ng of input (1 µg with automation). An FFPE-compatible protocol is also available.

This unique combination of features makes the HumanMethylation450 BeadChip a powerful tool to drive exciting new study designs and further fuel the rapid evolution of epigenetics research.
