# Can FFPE input be used with the Illumina DNA PCR Free library preparation kit?

**Does the Illumina PCR-Free kit work on damaged or degraded DNA samples such as FFPE samples?**\
For FFPE, it is recommended to use a PCR-based kit. However, for high quality FFPE, Illumina DNA PCR-Free may be suitable. This will need to be tested and validated by users.
