The undiluted XC4 reagent ships at room temperature.
Illumina recommends storing both undiluted XC4 and XC4 that has been diluted with ethanol at room temperature.
The diluted XC4 can be re-used up to six times over a two-week period for a maximum of up to 48 BeadChips.
After ethanol has been added to the XC4, Illumina recommends clearly marking the bottle as ‘diluted’ to avoid mix-up with any undiluted XC4 bottles. Cite the date of dilution to track the recommended two-week storage.
The XC4 reagent bottle label displays the expiration date of the undiluted reagent. Illumina supports its products within the expiration date.
