How long can bisulfite converted DNA be stored in 20°C for use in Infinium Methylation arrays?

If stopping after bisulfite conversion, heat-seal the plate, and store samples at -25°C to -15°C for up to 30 days. This information is found in the Infinium HD Methylation Assay and the Infinium EX Methylation Assay protocol.

For more information, refer to the following Illumina Knowledge articles:
