Since FFPE samples are prone to gDNA carry-over, it is recommended to perform a DNase treatment prior to library preparation.
When using CORALL FFPE, there are two options for DNase treating FFPE samples:
-
DNA Removal Add-on Module (Cat. No. 235) - instructions for utilizing this module in the CORALL FFPE workflow are provided in our User Guide (p. 9). Following DNA Removal, the final volume can be directly input into RiboCop.
-
SPLIT One-Step FFPE RNA Extraction Kit (Cat. No. 236 ) - a 15 minute DNase treatment is seamlessly included during RNA Extraction.
