Illumina will retain DMAP files for all Infinium beadchips for 24 months after the date of manufacture. Since shelf-life may vary between 12 months or 18 months depending on the Infinium beadchip, the DMAP would be retained for either 12 months or 6 months after expiration, respectively. Make sure to **download DMAP files prior to the expiration date** printed on the label to mitigate the risk of losing DMAP files. See the article "[DMAP files for all Infinium Arrays are available for two (2) years after the date of manufacture](https://knowledge.illumina.com/microarray/general/microarray-general-reference_material-list/000005602/?utm_source=agent\&utm_medium=email\&utm_campaign=kb)" for more information.

Notes:

* Refer to the label on the beadchip packaging for accurate expiration date.
* These expiration dates apply to commercial and custom arrays.
* Infinium reagents may have different expiration dates from the beadchips.
* For best results and reproducibility, use Infinium beadchips and reagents prior their expiration dates.
* Illumina guarantees that all Research Use Only (RUO) products will ship with a minimum viable shelf-life of three months from the date of shipment.
